I have a Forman grill at my office and use it all the time! My favorite is: garlic lime cilantro chicken breast
marinate a chicken breast the night before with a little lime juice, a clove of garlic and either fresh or dried cilantro (whatever i have on hand) with a teaspoon of olive oil in a zip lock bag.
For the lime juice I get the key lime juice in the bottle and always have some on hand in the fridge.
I also use it for halibit (same marinade) and tuna filet...YUM!
Enjoy!
