In a small saute pan coated lightly with oil, saute the black beans and garlic until soft, add the jalapenos, serranos, and saute 2 minutes, add the pork and cook about 8 to 10 minutes on low heat or until cooked through. Set aside and let cool.
Add the chopped cilantro and cheese. Stuff each chile full. Dip each one in the tempura batter and fry until golden brown, about 4 to 5 minutes. Season lightly with salt and pepper.
Plating: On a large plate, ladle each half with the red and green sauces, yin-yang-like, if possible. Place a small mound of rice in the middle of the plate. Top with a poblano chile, drizzle with cilantro crema, and garnish with a cilantro sprig.
In a large bowl, mix the cornmeal, and rice, and whisk in the soda until a pancake batter consistency is achieved.
Bandera Sauce Red:
Transfer all ingredients to a blender and puree until smooth. Season with salt and pepper.
Bandera Sauce Green:
In a saucepan, coated lightly with oil, add the onions and garlic and sweat until soft. Add the jalapenos, bell pepper, cinnamon, season, and stock. Reduce by 50 percent then transfer to a blender. Puree until smooth and check for seasoning.
Mix all ingredients together and refrigerate until needed.
