I'll join all the people here in praising the Foreman grill. It's great! you can cook so many things on it very quickly.
Burgers are easy to make. Veggie burgers taste pretty good and are definitely healthier. And if you want more options, salmon burgers taste great (they're less than 1$/patty at Trader Joe's too).
On a personal level, I like having lots of oregano on everything (I just eat it on its own sometimes.. but you don't have to
).. One small jar of it lasts for a while and isn't that expensive. It just gives a great taste to everything!
