Lightly spritz the crock of a slow-cooker with non-stick cooking spray or generously butter it. Stir together the sweet corn, black-eyed peas, cream cheese, Monterey Jack cheese, sour cream, garlic, salt, and crushed red pepper flakes. Put the lid on the slow-cooker and set the cooker to LOW. Cook for 2-3 hours, or until the contents are uniformly hot, the cheese is melted, and the corn and black-eyed peas are coated with a creamy sauce. While the mixture is cooking, finely chop the crispy bacon and reserve 1 tablespoon of the chopped bacon along with 2 teaspoons of the minced green onion. Stir the remaining bacon and green onion into the hot dip then scoop the dip into a serving dish. Sprinkle the reserved bacon and green onion over the top and serve with chips or as a side dish.

Leftovers can be stored, tightly wrapped, in the refrigerator for up to 5 days. Reheat covered but vented in a microwave on HIGH until hot all the way through.
