1. Cut the peppers into quarters, remove the seeds and membranes. Place the pepper pieces under the broiler, skin side up, and cook until the skin blisters and blackens.
2. Cook the pasta in a large pot of salted boiling water until al dente. Drain them. Cut the baby corn in half lengthwise and roughly chop the oregano.
3. Cook the corn and beans separately until just tender. Drain them. Melt the butter in a small saucepan and heat it, stirring well, for about 3 minutes until it turns a slightly brown color. Remove from heat, add the garlic and oregano, and set aside.
4. In a large dish, mix everything together, drizzle with flavored butter, gently stir, and serve.
