Looking for easy, cheap, and tasty recipes

I hate cooking. And what is more, I hate cleaning up after cooking. Pizza was my go to. I would buy pre made dough and whatever toppings suited my fancy, it was cheap and delicious and only needed one pan. But it made me gain weight.

So I'm looking for a healthier alternative. Something I can cheaply and easily make, that tastes good, and only uses one dish.
