Ingredients

1/4 c. mayonnaise or butter, for grilling bread

8 slices sourdough bread

1/2 jar marinara sauce (26-oz.)

1 container ricotta (14-oz.)

2 c. shredded mozzarella

Preparation

Step 1Spread butter or mayonnaise on one side of each slice of bread, putting each slice butter-side-down on a platter or piece of parchment paper. Step 2Spread marinara sauce on each slice of bread, then slather on ricotta. Sprinkle mozzarella cheese on every other sandwich, then assemble sandwiches.Step 3In a frying pan over medium heat, grill sandwiches until each side is lightly golden and the cheese has melted, 1 to 2 minutes per side. Step 4Let sandwiches sit for 10 minutes before cutting them into bite-sized pieces. (This keeps the ricotta from spilling out everywhere.) If serving later, place them on a baking sheet in a 200° oven until guests arrive.Step 5Serve with marinara sauce for dipping.
