I would give this a try. Though I am not a fan of mac & cheese with a tomato base so I’d probably go with a white sauce instead of tomato. I can see serving this with a nice salad and kielbasa sausage.

APPLE MACARONI ‘N’ CHEESE

Serves 4-6

½ lb bacon
1 onion, sliced or diced
½ lb elbow macaroni, cooked
8 oz tomato sauce
2 C applesauce
¼ lb shredded cheese
¼ tsp curry powder
1/8 tsp dry mustard
½ tsp Worcestershire sauce
Salt, pepper, to taste

Preheat oven to 350˚. Fry bacon until crisp, drain on paper towels, reserve 4-5 slices for garnish, and crumble remaining slices. Drain off all but 2 Tbsp bacon drippings and sauté onion in bacon fat. Combine crumbled bacon, sautéed onions, macaroni, tomato sauce, applesauce, cheese, curry powder, dry mustard, and Worcestershire sauce, season to taste with salt and pepper, turn mixture into a lightly greased 2 quart casserole, and bake 25 minutes. About 5 minutes before baking is complete, arrange reserved bacon slices on top of casserole.
