Saute garlic, onions, and pepper in oil till tender. Add 1 lb hamburger to pan, cook till no longer pink, drain. While stiill hot, in very large bowl, mix spaghetti, salt and pepper, jarred spaghetti sauce, the meat mixture and the Velveeta. Put in greased 9 X13 glass casserole or
baking dish. Cover with foil and bake. I have to be honest, the more Velveeta you put in the more the people rave about this. It truly is loved by all!!!
