Some dishes work well for appetizers or finger foods at a potluck dinner. A savory cheese ball with some crackers to accompany it can be an excellent choice. Try homemade hummus with pita bread or Brie cheese topped with a fruit sauce. An antipasti platter can also be transported easily to a potluck dinner. The platter can include pitted olives, cherry tomatoes, pieces of Italian sausage, cubes of provolone cheese, slices of sweet red and yellow peppers, and other vegetables, all arranged on a bed of lettuce.
