This is certainly a favorite around our house. I think I might have gotten this recipe off of one of those recipe cards in the meat department at Walmart, go figure :)
1 lb ground beef
1.25-1.5 lbs large shell pasta cooked and drained
1/2 onion, chopped
1 can olives, drained and sliced (or 2 cans pre sliced olives)
1 can diced tomatos, drained (you could also use about 1.5 cupsof halved cherry tomatos)
3 cups shredded cheddar
1 can condensed tomato soup
1 can milk (tomato soup can)
1 package of fajita seasoning (I really think this recipe tastes best with Great Value brand seasoning, I have tried others)
Brown beef with onion and drain.
Mix beef, onion, olives, tomatos and pasta. Mix together seperately tomato soup plus one can of milk and fajita seasoning. Pour this over pasta mixture and add shredded cheese.
Place in pyrex dish and cover with foil and bake at 375 for about 45 minutes.
This is also really yummy topped with crushed fritos!
