I did some cheddar brats, peppers and caramelized onions. Also some chicken sausage.
The brats were some of best I've had and an extremely simple marinade my dad said try out: Salt, pepper, soy sauce, garlic powder and I added some lemon juice. Put them on a potato bun with some caramelized onions and a dash of your favorite mustard. Dayummmm they were tasty.
Caramelized onions was also extremely simple and I know everyone has their way of doing it. My recipe: salt, pepper, butter and some brown sugar. After about 10-15min add a little bourbon. I used 4 Roses and was pretty conservative of how much I used, but just like the brats they were killer.
