Melt two tablespoons butter in a large skillet over medium heat. Add bell peppers, red onion, corn, and zucchini.
Sauté for 5-6 minutes until zucchini is tender. Season with salt, pepper, and paprika.
Remove from heat and let cool slightly. Stir in tomatoes, lime juice, cilantro, feta, cooked and drained pasta, and remaining tablespoon of butter. Mix well.
This pasta salad can be served warm or refrigerate until ready to serve.
