Heat oven to 350°F. In medium bowl, stir together beans, chorizo, chiles, tomatoes, hot sauce, cumin, scallions, cilantro and 1 cup cheese.
Spread bean mixture evenly in 9” shallow (1-quart) baking dish. Sprinkle with remaining cheese.
Bake, uncovered, until bubbling and heated through, about 25 minutes. Let sit 10 minutes before serving. Garnish with scallions and cilantro. Serve with plantain chips.
Skillet-Buddies Bean Dip: Prepare bean mixture as directed; spoon and spread into four 5” mini-cast iron skillets (or shallow 1-cup ramekins). Top with cheese and bake, uncovered, 15 minutes; then follow remaining directions as listed above in Step #3. Each skillet serves two.
