In a large skillet, heat the olive oil over medium heat. Add the chopped onion, poblano pepper, red bell pepper, and zucchini. Sauté for about 5-7 minutes, or until the vegetables are softened.
Stir in the minced garlic and corn, cooking for an additional 1-2 minutes until fragrant.
Add the rinsed black beans to the skillet. Sprinkle in the chili powder, cumin, smoked paprika, kosher salt, black pepper, and lime juice. Stir well to combine all the flavors.
Carefully pour the red enchilada sauce over the vegetable and bean mixture. Stir until everything is evenly coated and heated through.
Gently fold in the corn tortilla strips, making sure they are coated with the sauce. Sprinkle half of the shredded cheese over the top.
Cover the skillet and let it sit for about 5 minutes, allowing the cheese to melt and the tortillas to soften.
Once the cheese is melted, remove the lid and garnish with sliced green onions, chopped cilantro, diced avocado, and radish slices. Serve warm and enjoy your Skillet Vegetarian Enchiladas!
