Bring a large pot of salted water to a boil. Add the macaroni and cook according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process and cool the pasta.
1 lb elbow macaroni
Heat an indoor or outdoor grill over high heat and brush the corn with oil. Cook the ears of corn for a few minutes on each side until it starts to brown. Alternately, roast at 425 for 12-15 minutes. Cool and cut the kernels off the cobs.
2 ears (1 cup) fresh corn
Mix all of the dressing ingredients together in a small bowl or blender while the pasta cooks.
3/4 cup Greek yogurt, 1/3 cup sour cream, 1 lime, 1 teaspoon chili powder, 1 teaspoon cumin, 1 clove garlic, 1/2 teaspoon kosher salt
Combine the cooled pasta in a large bowl with the remaining pasta salad ingredients. Pour the dressing on top and toss to coat evenly.
1 cup black beans, 1 cup cherry tomatoes, 1 green bell pepper, 1/2 medium red onion, 1/4 cup fresh cilantro, 1 jalapeño
Cover and refrigerate for 30 minutes if possible, but serving at room temperature works too. Taste and add more salt or lime juice as needed. Top with fresh chopped cilantro and sliced jalapeno before serving.
