Today I am going to cook lentil salad.X

> Today I am going to make lentil salad > You make salad , soup and cake . You cook steak , vegetables and pasta . Cooking is normally for preparation of meals involving application of heat to the ingrdients in various ways.

It is a fast now and we can't eat products taken from animals such as milk, eggs, butter and so on.

> It is fasting time for us now , and we can't eat any animal products , such as milk. eggs and butter .

> Fast is an adjective or verb , not noun . He want to fast for 3 days./ The horse is fast

> You don't take products from animals > The word is never used . Just like you don't take an apple from a tree , you pick an apple from a  tree . A suitable phrase is " products obtained from animals"

Since I am breastfeeding, I can't fast but anyway once a week I am cooking fast meals without animal products.

> Since I am breastfeeding, I can't/am not supposed to fast , but I still a cook a break-the fast meal once a week anyway .

> "Since I am breastfeeding" is an introductory clause TO I cannot fast , so you must put a comma to pause before continuing the sentence, which is the main clause " I cannot fast"..

 > There not no such thing as "fast meal" , "fast food", yes , such as MacDonalds.

Lentil salad is very easy to make, and there are very few ingredients that are required to make one: just some lentil, carrots, onions and some oil.

> " Lentil salad is very easy to make" and " there are very few ingredients that are required to make one" are 2 independent sentences, meaning they can both standalone sentences -- you can put a fullstop between them instead of "and")--and there still retain the same meaning .

>Lentil salad is very easy to make because it requires only a few ingredients , which are some lentil, carrots, onions and some oil. ( Use "because" to explain why it's easy . it's becomes clearer )

> I use colon (:) because one of the main function of its usage is to clarify or explain what you mean earlier . A colon roughly means " By that I meean..."

You used a en-dash (-), which is wrong . You may use a em-dash (--) to carry the same point , but it should be stupid that its "surprising" or an afterthought that you wish to add, for example.

On Sunday, we are going to visit my in-laws. My mother-in-law is s great baker, and she always bakes fluffy cakes and not cakes that melt in your mouth like ice cream.

Plese look at this sentence : My mother -in-law is a great baker and always bakes fluffy and don't cakes which melt in a mouth like ice cream.

Without adding ", and she ..." , the construction is wrong because it means " my mother-in-law IS ( something)  and (IS )ALWAYS BAKES... You have to make the 2nd sentence independent by adding "she"

> After every introductory" time" phrase longer than one word , such as today, now and yesterday that do not reqiure a comma, use a comma to pause before continuing to what you want to say .
