Paleo-pescatarian? Anyone? Only the most relevant foods apply; dairy-free is out, gluten free is in, and absolutely no sugary snacks whatsoever (cakes, pies, donuts, pastries, candy bars, taffy, sweet tarts, chews, and mike and ike's, chewing gums, tic tacs, mentos, etc -- you get the picture).
Toss chopped peppers, potatoes, zucchini, red onion and sausage (I used turkey kilbasa) with olive oil, salt, pepper and garlic powder. Seal in an aluminum foil pouch and bake at 400 for 40ish minutes. You can also grill this.
