Mac and Cheese with Beef Bacon

2 cups cooked macaroni
Salt and pepper to taste
1 Harvest Haven egg, beaten
1 tsp dry or prepared mustard
1/2 cup milk
1 cup (or more) shredded Cheddar cheese
1/2 cup (or to taste) Harvest Haven beef bacon, cooked and chopped into bite-size pieces
1 – 2 Tbsp Harvest Haven onion, finely chopped (optional)

Combine macaroni, salt, pepper, egg, and mustard dissolved in the milk.
Stir in cheese, reserving enough to sprinkle generously over the top; mix well.

Turn into buttered 1½ - quart casserole, top with bacon bites and remaining cheese. If using the chopped onion, it can be spread in the bottom of the buttered casserole dish, then the macaroni and cheese spread on top of it.

Bake uncovered in 350°F oven 30 to 40 minutes or until knife inserted into center comes out clean.

Serves 3 or 4.
