Stuffed Shells

1 lb. ground beef
1 med. diced onion (I use flakes)
2 6oz. cans tomato paste
3 6oz. cans of water
2 Tbls. sugar
1 pkg. spaghetti mix
1 box jumbo shells
12 oz. carton cottage cheese
1 egg
1 lb. mozzarella

Put shells on to boil first. Brown meat w/onion. Add paste, water, sugar and spaghetti mix and let simmer. While simmering mix cottage cheese and egg with shredded mozzarella. Using a spoon-stuff the shells. Spread a little sauce on bottom of a 9x13 pan and line with shells. Cover in remaining sauce and top parmesan cheese if you like. Bake at 350 for 30-45 minutes, enough time for the cheese to melt.
