To make a vegetarian tofu tenderstem and black bean stir fry recipe, first you'll need to prepare your ingredients. First, you will need: 1 pound (240 g) vegetable oil, 2 tablespoons (60 ml) dried red chili powder, 1 teaspoon (0.5 tsp) kosher salt, and 1 tablespoon (2.5 fl oz) chopped fresh cilantro. Toss the vegetables with the oil and season with salt and pepper. Place the vegetable mixture in the pan and cook over medium-high heat, stirring occasionally, until the veggies are lightly browned, about 5 minutes. Remove from the heat and stir in 1 cup (250 milliliters) of frozen black beans. Serve immediately.
