Bacon is the surprising ingredient in these simple meatball sandwiches made with high-quality Sam's Club pork and beef. The whole family will love these for lunch or dinner, or whip them up for handheld party appetizers.
Place bacon in a food processor; cover and process until finely chopped. In a large bowl, combine the milk, egg, bread crumbs, onion and seasonings. Crumble the bacon, pork and beef over mixture and mix well. Shape into 2-inch meatballs. Place in an ungreased 15x10x1-inch baking pan. Bake at 425°F for 30 to 35 minutes or until a meat thermometer reads 160°F. Spread ranch dressing over rolls. Layer each with salad greens, a tomato slice and a meatball; replace tops.
