Burrito Zoodles

In a large skillet over medium heat, heat oil. Add onion and cook until soft, about 5 minutes, then add garlic and cook until fragrant, 1 minute more. Add ground beef, breaking up meat with a wooden spoon. Cook until beef is no longer pink, about 6 minutes. Drain fat. Stir in chili powder and cumin, then season with salt and pepper. Stir in black beans, cherry tomatoes, corn, enchilada sauce, and cheeses. Cook until cheese is melty, 4 to 5 minutes. Add zoodles and toss to coat in sauce, cooking just until warmed through, 3 minutes. Garnish with cilantro before serving, if desired.
