Cook the Beef: In a large skillet, heat oil over medium heat. Add ground beef and cook for 5–7 minutes until browned. Drain excess fat, sprinkle in taco seasoning, and simmer for 2–3 minutes.

Prepare Vegetables: Chop cabbage and dice tomatoes. Drain black beans and corn in a colander.

Layer Ingredients: In a large bowl, layer cabbage, seasoned beef, black beans, corn, and diced tomatoes, tossing gently to combine.

Add Toppings: Sprinkle Fritos and shredded cheese across the top, creating a deliciously cheesy finish.

Dress and Serve: Drizzle ranch dressing just before serving to maintain Fritos' crunch. Serve immediately.

Optional Toss: For a salad-like experience, toss ingredients together before serving.
