1 can "original" RO-TEL, undrained
4 oz. prepared black beans, fully rinsed
4 oz. frozen sweet corn kernels, steamed and warm
1 cup already prepared Basmati rice, warm
Mix everything together in a heat-proof covered casserole dish and pop it in the oven on "warm" 20 minutes or so before serving. The tomatoes in the recipe prepared this way remain perkier than cooking the RO-TEL together with the rice.
You don't have to make your beans from scratch, but I did. Took about 3 hours. Rinse, cover with water in a heavy pot, boil, turn off heat & cover 1 hour. Return to boil, then to low, simmer 2 hours covered. Drain and rinse well. Ba-da-bing.
