First of all I wanted to say that I am sorry for the recent losses that you have gone through. It must have been very hard to go through both so close together.
As far as the food goes, I think contributing to the trays and making a fruit salad was a good idea. If you wanted to make something yourself a casserole that can be frozen is always nice. This way if they have a lot of food they can freeze it to use later in the week.
Here's a couple casserole recipes for you:
Turkey Tetrazzini
1 pkg (8 oz) spaghetti broken in 3" pieces, cooked, drained
1 1/2 cups grated Cheddar cheese, divided
1/4 cup Parmesan cheese, divided
2 cups diced cooked turkey
2 tablespoons diced pimientos, if desired
1/4 cup chopped onion
1 can cream of mushroom soup
1/2 cup chicken broth
1/4 cup dry sherry
salt and pepper, to taste
Combine spaghetti with 1 cup Cheddar cheese, half of the Parmesan cheese, and remaining ingredients. Toss together; place in a greased casserole and sprinkle with remaining cheeses. Cook at 350 degrees F., covered, for about 45 minutes, or until hot and bubbly.
Serves 6 to 8.
Cheddar Beef and Noodle Casserole
1 pkg (8oz) noodles, cooked & drained
1 1/2 pounds ground beef, lean
1 medium onion, chopped
1 jar (15oz) spaghetti sauce
1 can Cheddar cheese soup, (10 3/4 oz)
1 can tomato sauce, (8 oz)
1 can or jar sliced mushrooms, (4 oz)
1/4 teaspoon garlic powder
pepper, to taste
2 cups shredded Cheddar cheese
In a large skillet, brown ground beef with chopped onion; drain well. Stir in spaghetti sauce, soup, tomato sauce, mushrooms, garlic powder, salt and pepper. Simmer for 3 to 4 minutes. Combine beef mixture with cooked noodles; pour into a 3-quart baking dish (may use 13- by 9-inch baking pan). Cover and bake at 350 degrees F. for 35 to 40 minutes, or until bubbly. Uncover; sprinkle with cheese, and bake just until cheese is melted.
Serves 8.
