Instructions
Sprinkle seasoning salt over the entire tri-tip. Place tri-tip and water or broth in the slow cooker and cook on high for 3 to 4 hours or low 6 to 8. The meat is done when you can easily pull it apart with a fork. Use two forks to shred the meat in the slow cooker.
Preheat the oven to 400°F. Spread mayonnaise over the inside of the rolls and top with the shredded tri-tip and shredded cheese. Bake for 5 to 6 minutes until bread is toasted and cheese bubbly.
Add BBQ sauce and enjoy!
Notes
*If you don't have seasoning salt, mix together 2 teaspoons each of salt, pepper, and garlic powder.*If you buy an untrimmed tri-tip, just cut off as much of the layer of fat as you can before adding the seasoning and cooking.
