Ingredients:
Nonstick cooking spray
2 tablespoons vegetable oil or olive oil
2 large onions, finely chopped (2 cups)
1 pound ground beef
2 15-ounce cans Boston-style baked beans
2 medium tomatoes, finely chopped (1 cup)
1/4 cup packed light brown sugar
1 tablespoon Dijon mustard
1 1/4 teaspoons salt
1/2 teaspoon freshly ground black pepper
5 slices bacon
Instructions:
Preheat oven to 350°F. Coat a 2-quart casserole dish with cooking spray; set aside.
In a large skillet, heat the oil over medium heat. Add the onion; cook about 5 minutes or until softened. Add the beef; cook about 10 minutes or until brown, breaking meat up with a fork as it cooks.
In a large bowl, combine the beef mixture with the remaining ingredients except the bacon; mix well. Pour beef mixture into the prepared casserole; arrange the bacon slices on top. Cover with a lid or aluminum foil. Bake about 45 minutes or until thick and bubbly. Uncover dish and preheat broiler. Broil for 1 to 2 minutes or until the bacon is crisp.
