Grilled Corn Bread and Mozzarella Melts

Make the corn bread:

Preheat oven to 400°F. Line a 9- by 12-inch pan with parchment paper, butter the paper, and set aside. Melt the butter in a large skillet over medium heat, add the onions and pepper, and cook until softened -- about 5 minutes. Place the buttermilk, egg, sour cream, and pepper in a large bowl and whisk to combine. Add the corn-bread mix and stir until combined. Stir in the onion mixture. Pour the batter into prepared pan and spread evenly. Bake for 12 minutes and transfer to a wire rack to cool.

Assemble the sandwiches:

Lift the parchment to release the corn bread from the pan and use a cookie cutter to cut twenty 2-inch rounds from the bread. Discard the scraps. Spread 1/2 teaspoon of chutney on 10 rounds. Evenly divide the cheese among the 10 rounds and top each with a remaining corn-bread round. Heat a large skillet over medium-low heat and lightly brush each sandwich with olive oil. Place the sandwiches in the skillet, 5 at a time, and grill until the cheese melts and the bread is golden -- about 2 minutes on each side. Serve immediately.
