Cook the pasta: Bring a large pot of salted water to a boil. Cook the pasta until just al dente.
Drain and rinse under cool water to stop the cooking. Toss with a tiny drizzle of olive oil so it doesn’t stick.
Char the corn: Heat a large skillet over medium-high. Add the corn (no need for oil if using a good nonstick).
Cook, stirring occasionally, until lightly charred in spots, 5–7 minutes. Season with a pinch of salt. Let cool.
Make the dressing: In a bowl, whisk Greek yogurt, light mayo, olive oil, lime zest and juice, chili powder, cumin, smoked paprika, garlic, honey, 1/2 teaspoon salt, and a few grinds of pepper.
Taste and adjust lime or salt as needed.
Prep the veggies: Finely dice the red bell pepper, red onion, and jalapeño. Chop the cilantro.
Combine: In a large mixing bowl, add cooled pasta, charred corn, bell pepper, onion, jalapeño, and cilantro. Pour over the dressing and toss until everything is coated.
Add cheese: Gently fold in the crumbled cotija or feta.
Reserve a little for topping.
Chill: Cover and refrigerate at least 30 minutes so the flavors come together. Taste again before serving and adjust salt, pepper, or lime.
Serve: Top with extra cotija, more cilantro, and a sprinkle of chili powder. Add avocado or a dash of hot sauce if you like a kick.
