Tips

• Grease the Slow Cooker Well: Prevents sticking.

• Don’t Overcook: Check for doneness around the minimum cook time.

• Use Freshly Shredded Cheese: Melts better than pre-shredded.

• Add Veggies: Spinach or mushrooms work great.

• Let It Rest: Allow a few minutes before slicing for cleaner servings.
