Im a college going guy who lives in a house alone that likes to cook for himself, so Ive learnt how to make obvious stuff like pizza, pasta, local specialities and so on, but now that Im weighing 95kg, I realize I gotta make some healthy stuff as well, so can someone tell me some good and easy stuff to make? Im vegetarian BTW.
Ty in advance :)

Tofu stir fry has always been one of my favorite things to make. You just fry some tofu and veggies in a pan and add stir fry sauce and you're good to go.

Italian style Pasta is fairly simple and fairly healthy. Bowties, Noodles, Etc.

Just boil noodles and get sauce. If you are able to make instant ramen, you should be able to make this with instructions.
You could also make homemade Macaroni and Cheese, it is healthier than Kraft. I hear Swiss cheese in particular is one of the healthier cheeses.

Finally if you have a bit of a budget, you could get a blender to make smoothies and protein shakes.

That food looks good
