Goulash and Pizza Casserole are favorites of the current group, toddlers and preschoolers alike.
Goulash is elbows, ground beef, pasta sauce with paprika added.
Pizza casserole is rotini, ground beef, pasta sauce, pepperoni and topped with mozzarella shreds.
For each of these I add either purees of pumpkin or squash to the sauce to sneak an extra veggie in. Also makes the sauce a little sweeter. Also, while I haven't done it yet, it is on the next menu cycle to add kidney beans to the Goulash, which is how my mother always made it and is sneaking in more beans in to their diets. Of course, they will likely leave a pile of beans on their plates...
