Notes
Meats: Swap ham with other deli meats like turkey or roast beef.
Vegetarian: Replace ham with thinly sliced veggies like bell peppers or zucchini.
Add-ins: Consider sun-dried tomatoes, olives, pickles, or jalapenos for extra flavor.
Sauces: Try different sauces or spreads such as honey mustard, barbecue sauce, or a garlic herb spread.
Extra Cheese: Sprinkle shredded cheese on top before baking.
Make ahead of time by covering the prepared rollups with plastic wrap and refrigerating them. DO NOT bake. When ready to bake, remove from fridge and bake uncovered.
