Preheat oven to 350°.
In a mixing bowl, add the Blue Runner® cream style red beans, salsa, lime juice, and ½ teaspoon of salt. Stir until well blended.
In a separate mixing bowl, add the mayonnaise, 1 teaspoon of salt, granulated garlic, granulated onion, cayenne, diced pimentos, and green onions. Mix until well blended. Add the grated Cheddar and Pepper Jack cheeses. Stir until well blended.
Line the bottom of a shallow baking dish with the red bean mixture. Spoon the pimento cheese mixture over the red beans, covering the entire surface.
Bake at 350°, uncovered, for 20 minutes. Remove from oven and serve with corn tortilla chips, pita chips, or crackers.
