In a skillet over medium-high heat cook beef and onion until brown, about 7 minutes. Drain oil and discard. Add diced tomatoes, honey, Worcestershire sauce, and ground mustard. Bring to a boil. Pour into a square baking pan.
In a medium bowl mix together cornbread mix, milk, oil, and egg.
Spoon cornbread over the meat mixture and top with cheese. Bake until a toothpick inserted comes out clean, about 30 minutes. Serve hot.
Notes
Make sure the cornbread is cooked all the way through by testing with a toothpick.
Make mini sloppy joe casseroles by cooking these in muffin tins. So fun!
Perfect Pairing
End your meal with this Banana Pudding Parfait. Yum!
