Tin Foil Dinners - my inlaws taught me how to make these and they are so easy and good! You can put whatever you want in them but we usually do: ground beef, carrots, potatoes, tomatoes, onions, and peppers. Then add garlic salt and lawrys seasoning salt and a few pads of butter to keep it from getting too dry. This recipe says to put them on a campfire but this works great on a gas grill too.
Easy Grilled Banana S'mores Recipe - banana sliced down the middle & stuffed with marshmallows & chocolate chips. Throw it on the grill or in the oven for a few minutes. Ta da! (for a little extra yumminess, I'd add peanut butter chips too)
