The original recipe (which is such a 1950's kind of recipe) calls for a packet of sloppy joe mix, but I season the sauce myself. This allows me to adjust the spice level for my kids and avoid whatever oddities are lurking in those packets!
Sloppy Joe Casserole
1 lb ground turkey
1 small onion, diced
8 oz small pastas (elbows or shells), cooked
16 oz small curd low-fat cottage cheese
1 large can tomato sauce (15 oz, I think?)
2 Tbsp worcestershire sauce
2 tsp dry mustard
1 Tbsp white vinegar
onion & garlic powder
Optional: shredded cheddar cheese for topping
Cook the turkey and the onion together. Toss in a large bowl with the pasta and the cottage cheese. Preheat the oven to 350F.
In a medium bowl, whisk together the tomato sauce, worcestershire sauce, mustard, and vinegar. Add onion powder, garlic powder, and pepper to taste (and more worcestershire or mustard - or add some Tabasco to give it kick!). Don't add any salt - the cottage cheese is pretty salty already. Pour the sauce over the pasta mix and stir well.
Pour the pasta mix into a 2-qt casserole dish. (Optional: top with shredded cheddar cheese) Bake until heated through, about 25-30 minutes. This dish can be prepared early in the day and baked at dinner time.
