Hello and welcome to HCM
There is a good variety of foods in vegetarian group.
Boiling vegetables and adding sauces of your choice is a good option.
Take care of proteins
in your diet because the amount of proteins in vegetarian food is less than that in non-vegetarian food.
Soyabean and cheese are rich sources of protein.
The bioavailability of iron in vegetarian foods is less than that in non-vegetarian foods. Iron rich foods are greeny vegetables.
There are many recipies available in the market. You can try them.
Thanks and take care
