Here's what you need to eat. Please make a note of the pulses and vegetables which I've mentioned. Apart from those mentioned, it would be beneficial to purchase fruits and vegetables which are native to your region so that you can formulate your own recipes in the future.
You need to make sure you eat pulses at least three times a week and fruits and vegetables everyday.
Have a fruit for breakfast(apart from something else of course) and vegetables/pulses for lunch and dinner.
Make sure you include ALL varities of fruits, vegetables, pulses, grains, nuts, seeds and dry fruits in your grocery list.
Don't eat mock meat and soybean as mock meat contains sodium and soybean is bad for health.
Mock meat is also soy based so too much soy can be bad for health.
Actually even a little soy is bad for health.
What's wrong with soy?
Soy beans are naturally toxic to humans, but they're harmless when they go through a fermentation process, which is how we get tofu.
But soy is being used in more and more things these days.
Just look through your cabinet. You'll be surprised.
Anyway, most companies aren't putting their soy beans through this process because it takes too much time, and time = money.
Instead, they put it through a chemical process, but this rarely gets rid of the soy's toxicity completely.
Symptoms of a high soy diet are thyroid problems, breast cancer, and other complications.
People get these symptoms because the soy they eat isn't fermented.

Mock meat can never be part of a staple diet(food what you eat everyday) as it is highly processed.
You CAN have it ONCE IN A WAY.
Its a luxury and not a need.
Now looking at a staple diet, You'll need to consume naturally occurring FRUITS,VEGETABLES(cauliflower,carrot, potato, beetroot, broccoli, okra, eggplant, radish, turnip, cabbage, bitter gourd, spinach,capsicum(aka bell peppers)),PULSES(chickpeas,kidney beans,black eyed peas,green gram,black gram,lentils,lablab bean,moth bean,horse gram,cow pea,double beans),NUTS(cashew nuts,peanuts,walnuts,pistachios,raisins) and GRAINS.
Also, do have figs once in a while as it is good for blood purification.
Make something like rice and bread your staple diet.
You can have rice with vegetables or lentils/legumes for lunch and bread(I have Indian bread usually) with pulses for dinner.
You will get all vitamins and minerals from fruits,vegetables,pulses, legumes and nuts provided you consume them in variety so don't fall for the myth that says vegans/vegetarians need to take multivitamin supplements.
Vegans/vegetarians don't need to take supplements as they get all their nutrients from the above mentioned sources.
Supplements are supposed to be taken by people with deficiencies so do not take them UNLESS they have been prescribed to you by a doctor.
