You can't go wrong with panini made with wholesome ingredients like baby spinach, tomatoes, green and red bell peppers, as well as a layer of Sargento® Sliced Cheddar-Mozzarella Cheese that melts perfectly when toasted.
Brush one side of each bread slice with oil. Place on a work surface, oiled side down, and spread with mustard. On bottom halves, layer with Cheddar-Mozzarella, tomato, spinach, salt, pepper, bell peppers and Swiss. Cover with bread and press gently.
Place sandwiches in grill; close the top plate, and cook until golden brown, 3 to 4 minutes. Serve immediately.
