Meatloaf Sandwiches

Preheat oven to 375 degrees. In a medium bowl, combine chopped onion, garlic, parsley, egg, and 1/3 cup ketchup. Add breadcrumbs, beef, and pork. Season with 1 1/2 teaspoons salt and 1/2 teaspoon pepper. Mix until well combined.

Place mixture in a 6-cup capacity loaf pan (8-by-4-inch). Pat gently to form a rounded top; do not pack.

Bake meatloaf 50 minutes. Remove from oven; brush with remaining 1/3 cup ketchup. Return to oven; bake until an instant-read thermometer inserted in center of loaf registers 160 degrees, 10 to 20 minutes. Cool meatloaf 10 minutes in pan before removing.

Cut warm or cold meatloaf (see note) into 6 portions; place one on each of 6 slices of bread. Layer with lettuce and red onion, if using, and top with another slice of bread. Serve with additional ketchup, if desired.
