cook tasty, healthy vegetarian meals

I am no cook. I can usually cook up a tasty meal, so long as there is a central piece to it, ie:meat, poultry, or seafood. I’m not really fond of meat or poultry as a whole, and I find I cook way too much of them when I do, and I really hate leftovers as well. I could eat seafood every day of the week, but that can get a bit pricey. So I’d like to learn more veggie dishes. Usually when I have to meat, I’ll just make a bunch of appetizers/side dishes, which are really good too, but I’d like to make some good veggie meals as well.
