I love cooking hamburgers on that thing, it's awesome. If you hang the front of the grill over the sink you don't need that nasty ass little grease tray. As for the chicken, I'm no chef.

I just thaw out some chicken and marinate it in a ziplock bag with some marinate that you can buy at the store. You can get all kinds of flavors and the cheaper stuff is the same as the more expensive. Then you can just wipe it off with a paper towel when your done.

you can also prop the front legs up so the grilling surface is flat and pour your marinade right on the meat while cooking it.

I cook the chicken breast right out of the freezer all the time but here a tip leave the top open till the breast is half way cooked on the bottom side cause the top cooks faster then the bottom does. At that point I flip the breast over and close the unit and cook till done.

The key to Chicken is; Don't fear the seasoning. I use tons O' crap. I flick my wrist with the jar to get a good fluffy puff of Garlic, just a pinch of Lemon chicken, cover it with dried onion, some seasoning salt, salt, pepper, crushed red peppers, "Italian" seasoning. there’s tons of different flavor you can get by mixing the seasonings, and never forget the ease of spreading BBQ sauce once its cooked with no seasoning. I throw my breast on frozen solid.

Also, I cook Hamburgers and grilled cheese. Costco has pre cooked chicken breast at 20grams protein each, 2 minutes in the microwave for a quick protein boost vs a $3.00 chalk bar.

I marinate my chicken breast in low fat sundried tomato and oregano dressing. I usually put it in a ziplock with the chicken and let it marinade over night.
