READY IN: 1hr 5mins
Recipe by baby butterbean

I got this recipe years ago in high school. After moving overseas and not being able to find the large pasta shells I adapted it. I have made this and sold it for fund raising for a military function and made a killing! It is great and quick and everyone loves it! Hope you enjoy!

I really liked this, but changed it quite a bit partly because of what KLYN said about it being not saucy enough. I used 2 lbs. of meat and sauteed it with garlic powder, and Adobo seasoning, adding alot of fresh garlic and the peppers after a few minutes and sauteeing all together. I also added 1 small can of sliced black olives to mixture. I used no water and 16 oz. tomato sauce and 16 oz. of Picante sauce instead, added another cup of cheese to recipe and put 1/2 in the mixture and the rest of top. I also put all the French-fried onions, uncrushed on top and baked it partly covered and partly uncovered, adding the cheese and onions and baking for another 10 minutes or so. My family raved about it and it was truly delicious and moist. Thanks baby butterbean!
