Grill chicken or steak and then cut into thin strips. (Or use left over chicken or steaks) Slice red, green, and yellow bell peppers and onion. Put veggies and meat into a ziploc then add the italian dressing, salsa, and lemon juice. Let marinate for atleast 1 hour (the longer the better). When ready to eat grab large skillet and dump everything from the ziploc bag in. Cook until all the meat and veggies are cooked through. Serve on flour tortillas and top with cheese and sour cream!
