I know, this isn't difficult, but figured I'd post it just to give someone the idea. We had not made them in about a year because we just never thought about it.
Ingredients:
Stew Meat or whatever else you want
Red, Yellow, and Green Peppers
Grape Tomatoes
Mushrooms
Directions:
1. Dice everything up.
2. Put on skewers (don't forget to soak the wooden ones first if you use them)
3. Grill on medium heat about 5 minutes per side.
You can use whatever you want to for seasoning on the meat. A marinade would be good. We just use olive oil to coat the meat, then seasoned with black pepper, seasoned salt, blackened seasoning, garlic, coriander, and a bit of paprika. Turned out very good.
