Cook rice according to package instructions. To save time, use some type of microwavable rice packet or container. I like Minute Rice Ready to Serve or Seeds of Change brand.
Roast pepper, onion and corn on a baking sheet at 400 degrees F. for about 20 mins.
Cook black beans in small pot, over the stove, over low heat.
Meanwhile, heat 2 teaspoons olive oil in a large skillet, over medium-high heat. Add garlic to pan; saute 30 seconds. Add salt, chili powder and shrimp to pan; saute 2 mins. Add green onions and flip shrimp; saute another 2 mins and until shrimp are done. Once cooked; remove shrimp from hot pan so as not to overcook.
Assemble bowl with all of your favorites and enjoy immediately.
