I started my for family get together's about 10 years ago. It was a big hit right away. My brother take it to his Sunday school class meeting. Now they sign him up for each month. It make him feel good.
Open all items, place roast beef into drainer and wash off the gravy. Place all item into a slow cooker and put on low for 4-6 hours. Stir during warming time, to help everything come together. Let it get warm and the cheese to melt. Serve over chips or on a taco salad. Enjoy!!
