Mini Meatball Appetizer Cups are the perfect finger food for any party or gathering. This is an easy appetizer recipe that people of all ages will love! This recipe has a very pizza-like flavor and that is what makes these muffin cups so popular. I love that these don’t require a fork to eat! This is a simple recipe to double or triple for a big party. It is also a fun recipe to have kids help you make! Set up a little assembly line and put those children to work.
