Pritikin Recipes

I am not proud of my weight.
Even though most people think that i am smaller than i really am.
Well, i need help with a healtier diet.
Both my parents work kinda late [9-11ish] so they usually will bring home fast food.
Well, im getting sick of that, & i wanna look nice for summer.
We do go grocery shopping, but, i cant cook worth anything.

Can anyone give me some beginner tips on cooking?
& Something that is fast to cook also.
Nothing with any type of seafood//fish or eggs[like, scrambled, fried. cos, i will NOT eat eggs.]

Thanks.
To everyone:
Please read everything.

NO EGGS OR FISH.

Thanks!

My question again was about diet cooking tips and there have been some great answers
