I bet you're a better cook than you're admitting to. These should work on your grill:

HERB GRILLED CHICKEN (serves 4)
2-2 1/2 lbs chicken parts
3/4 cup vegetable oil
3/4 cup fresh lemon juice
2 tsp seasoned salt
2 tsp paprika
2 tsp dried basil
2 tsp dried thyme
1/2 tsp garlic powder (or 1 clove garlic, minced)

Wash the chicken & put in a heavy zip-lock bag. Combine the remaining ingredients & pour over the chicken. Seal the bag. Marinate in the refrigerator several hours. Broil or grill the chicken 4" from the heat source for 15-20 minutes per side or until done. Baste often w/the marinade.~~Udderly Delicious

SALMON WITH GINGER BUTTER (serves 4)
3 TBL dry sherry
2 TBL soy sauce
1 TBL dark Asian sesame oil
1 TBL minced fresh gingerroot
2 TBL minced fresh parsley
2 lbs salmon fillets
2 TBL butter, cut in small pieces
1/8 tsp salt
1/8 tsp pepper
1 lemon, cut in wedges

combine the sherry, soy sauce, sesame oil & ginger. Brush the fillets w/the sherry mixture & sprinkle w/parsley. Dot butter evenly across the surface. Season w/salt & pepper. This may be prepared several hours ahead & refrigerated.
Broil or grill the salmon without turning until the fish turns pink & flakes easily, approximately 10-15 minutes. Serve w/lemon wedges.~~Gold'n Delicious

GRILLED CHICKEN BREASTS (serves 6)
3-4 cloves garlic, crushed
1/2 cup firmly packed light brown sugar
3 TBL whole grain mustard
2 TBL apple cider or dry white wine
Juice of 1 lime
Juice of 1/2 large lemon
1/2 tsp salt
1/4 cup + 2 TBL olive oil
Pepper
6 whole boneless, skinless chicken breasts

In a small bowl, combine the garlic, brown sugar, mustard, vinegar or wine, lime & lemon juice & salt. Whisk in the oil & pepper to taste. Place the chicken in a shallow glass dish (or ziplock) & cover w/the marinade. Refrigerate at least 8 hours, turning once.
Remove the chicken from the refrigerator & let stand at room temperature 15 minutes. Grill over hot coals or broil 4 minutes per side or until the juices run clear.~~A Taste of New England

A better question is, what can't you cook on them?

There's even a national intercollegiate cooking contest in which they have to prepare everything from appetisers to deserts using the grill.

If you search under George Foreman Grill you'll find all sorts of sites offereing recipes for them. Here's one to get you started.
