Simple: fry one side on the first two, flip one and put in the third piece, then take out the completely fried piece and fry the other side of the second and third pieces.

For something easier to visualize, let the three bread slices be named 1, 2, and 3. Each of them has two sides: side A and side B.

Minute one: frying 1A and 2A.

Then flip 1, take out 2, and put in 3.

Minute two: frying 1B and 3A

Then take out 1, flip 3, and put 2 back in.

Minute three: frying 2B and 3B.

All three are done in three minutes.

"At dinner, the buffet is even cheaper" is correct. The second one is not correct because "the" never comes between a possessive and the thing it owns. "Dinner's the buffet" is wrong, but "dinner's buffet" is correct. If it were correct, it would be "Dinner's buffet is even cheaper." You would also not say "the dinner's buffet" because we don't use articles in front of collective nouns (most of the time) and "dinner's" is a collective noun here.

Other correct sentences:

"The dinner buffet is even cheaper." (Here, "dinner" is an adjective, so "the" belongs to "buffet".)

"The buffet is even cheaper at dinner."

*"My best friend said to me" and "My best friend told me" would both be correct here. "Said" is speaking out loud without directing it to a person, so there has to be a "to"  to explain who it is said to. "Told" is talking to a person, so it does not need "to" because that is part of the word.

**"Swum" is also technically correct, but people rarely use it. It is more common to use the phrase "go swimming" to describe the activity.

***Both "ask my mom for a new swimsuit" or "tell my mom that I want a new swimsuit" would be correct. 

For letters not in my alphabet, I grabbed a text expander plugin for my browser and set it to turn certain key combinations into the target letters. They're normally meant to turn small bits of text into larger phrases so that people can type more quickly, but they can pretty much be set to turn any combination of letters into anything else. The only problem is making sure it's not something you use in other contexts. For instance, it would be a bad idea to use the letter i for í, because that would change every i you use into an í.

I'm learning Spanish and Norwegian, so the letters I needed were á, é, í, ó, ú, ñ, æ, å, and ø. For the first five, it's the vowel immediately followed by a / because the slash looks like the diacritic, so i/ for í. (It's not turning into the character there because I typed them separately and got rid of the space between. It only works if they're typed together.) The ñ is the tilde right before the n, so ~n, which some people use in place of ñ. For the Norwegian letters, they're the typical transliteration of the letter (ae, aa, oe respectively) followed by an i (e.g. aei for æ) because I haven't seen any words with those vowel clusters in NO, ES, or EN. Granted, it does take a tiny bit more effort than just using ae for æ, but I'd rather use the correct letters and it's easier for me than using the alt codes. 

1) Not important. Other than political stuff, it's only a(n annoying) factor when people try to convert me or involve me in rituals designed to figure out which members of the pantheon are my spiritual family. Still not sure what that one was about.

2) I'm an atheist, so I don't have one. That should probably answer the question of born again or evangelical.

3) Only when there's a major event. For instance, I went for my great-grandmother's funeral (Catholic) and I'd probably go for a wedding, but I wouldn't go regularly or for holidays.

4) Definitely liberal, but not sure if I'm very or somewhat. I'm strongly for certain liberal social values. I also don't like conservative fiscal values, so I'm not libertarian (liberal on social values, conservative on fiscal values and guns; it's the third largest party in the US). If you're curious, though, most born-agains and evangelicals tend to be conservative, though there are certainly some exceptions.

You were close on both of them, but too mild. "Enorme" and "necesitar" are both stronger words.

"Enorme" is a cognate for the English word "enormous". It doesn't just mean big, but bigger than big: gigantic, humongous, immense, colossal. Lions are big. An elephant is enormous. "Huge" and "enormous" are close synonyms, and most apps and dictionaries will accept both translations for the same word. 

"Necesitar" is similar to "need", which is closer to the word "require" than "want". If you are very hungry, then you require a sandwich. It can overlap with "want" at times, but it's usually much stronger. If you want something, then you desire it, but there won't be negative consequences if you don't get it (besides disappointment). If you need something, then there will be negative consequences if you don't get it. For example, if you need a sandwich but don't get one, you might be too distracted from hunger to keep working well, or you might even pass out from lack of food.

The two Spanish words can be used whenever you would use their English counterparts, though you would only use "enormes" for plural words and "necesito" when you need to use the first-person present-tense singular.
