Welcome to the club. I've had one for years now. Here are some of my favorites in no particuar order.
Whole chicken. Coat heavily with Trager's chicken rub (not the pork and poultry rub.) Smoke for about an hour then crank tye heat to 350* until a thermometer reads 165*. It usually another 30 to 45 minutes. Claim the wings and legs for the chef and carve the rest like a turkey.
Squash. Any kind or mix and match. Cut into slice or strips and put in a bowl. Drizzle with some olive oil and shake to coat. Same thing with a veggie rub of some kind. Cook unitl tender.
Pizza. Make your pizza any way you want. I usually roll dough out on a cookie sheet for convenience. Cook on 350* until done. Delicious.
Ribs. I always do baby backs and use Traeger's 3-2-1 method. Experiment with rubs and sauces until you find a combo you like.
Sausage fatties. Take one tube of Jimmy Deans spicy sausage. Carefully cut it open to preserve the shape. Cover thick and heavy with sweet rub. Carefully roll it onto the grill and cooks until temp reaches 165*. Slice and serve with crackers and cheese. These are great appetizers or snacks. I usually throw one one when I'm doing a long smoke and let it cook slow for a coiple hours. A nice snack around lunch until your brisket or butt gets done. You can also throw it on a high heat cook as well. Very versitile and it will disappear quickly.
Chicken wings and/or legs. Coat liberally with chicken rub and cook on 350* until done. Toss in whatever sauce you like and back on for a few minutes to set the sauce. Simple and better than fried wings.
Taters. You can throw hole potatoes on while your cooking but they will take a while. I usually cook in the microwave until done. After that, cut in half and rub on some olive oil. Season the cut sides with chicken rub. It doesn't take a lot. Put them on the grill cut-side down and let them crisp up a little. Best spuds ever.
Sweet potatoes. Cut into strips like steak fries. Toss in a little olive oil and season with sweet rub. Spread on the grill and cook until done. At the end, push them together and sprinkle with a little brown sugar. Pull them off when it melts.
I've got more if you're interested. One top though is use foil on the drip pan and change it often. I use my grill a lot and change the foil every couple of weeks at least. Always make sure if is freash if you are going to do anything onver 350*. The stuff on there starts to burn and you can taste the difference.
