First thing that popped into my mind was PIZZA...
Pre-cook the sausages and slice to make a topping (if they are the thick sausages), or cut into small chunks if they are the thin ones.
The recipe we use is here:
Recipe Details - Robin Hood
We make 2 large cookie sheets of chili-cheeseburger pizza each Friday, and we have leftovers until Sunday night. One cookie sheet worth can feed 3 adults and 2 kids, but we have had other nights where the 4 of us ate 1.5 pizzas.
Basic toppings are sauce, then 454g cooked ground beef with chili powder and onion flakes added while cooking, then cheddar cheese, 2nd topping (tomatoes or other meat) and then mozza cheese on top (pepperoni on top of that if used). Last week I also added tiny chunks of breakfast sausage (beef/pork mix), and it was a hit. If we have bacon in the freezer, I will pre-cook that, chop it into tiny pieces and add it during the last 5 minutes of cooking. (Can you tell we've done this almost every Friday in 2008?) Most of these can be done up in advance and thrown in the freezer until you want to make a pizza too.
Nice thing with the pizza is that the kids can help to "decorate" it, and may eat it better when they get tired of sausages.
