Preheat the grill to medium-high heat.
Brush corn with olive oil, and season with salt and pepper. Grill for 5 to 6 minutes, rotating on all sides, until the corn has some nice charred spots. Let cool and remove corn kernels from the cob.
Add corn, brown rice, beans, red bell pepper, jalapeno, and green onions to a large bowl.
In a smaller bowl, whisk together the olive oil, lime juice, cumin, garlic, coriander, and salt and pepper. Fold dressing into the veggies and top with the crumbled cheese and toss.
Cook's Note: Queso fresco translates to "fresh cheese." It has a crumbly texture and slightly acidic flavor. Feta cheese can be substituted.
Cook's Note: Pinto beans have a delicious creamy taste and texture.
