I didn't make this in the slow cooker. I made the meat and onions and garlic, drained, mixed in the spices, then the tomatoes (drained) and sauce. cooked the pasta, then mixed that in. Then I placed it all in a 9x13 dish and topped with the cheeses and cooked at 350 for 30 minutes.
SLOW COOKER SLOPPY JOES are made right in the crock pot with ground beef, ketchup, a little brown sugar, worcestershire sauce, and a few other ingredients that you already have on hand. It is easy, saucy, and can be made with turkey as well for a healthy alternative to the ground beef.
