In a small bowl, whisk together oil, lime juice, chiles, honey, and salt.

In a large pot of boiling salted water, cook pasta until al dente according to package instructions. Drain and transfer to a large bowl. Add half of the dressing and toss to combine.

In a large skillet over medium-high heat, arrange beef in a single layer; season with salt and pepper. Cook until no pink remains, about 5 minutes. Drain excess fat, then add chili powder, garlic powder, cumin, onion powder, and paprika. Continue cooking for a minute.

Add pasta, onion (if using), bell pepper (if using), beans, corn, tomatoes, and remaining dressing to the skillet; season with salt. Fold in cheese and scallions until the cheese is melted, about 3 minutes.
