Prepare RightRice according to package instructions and let cool.
Coat the corn kernels in olive oil and season with sea salt. Gently char in the oven under the broiler setting. Let cool.
In a large mixing bowl combine prepared RightRice, diced bell peppers, black beans, red onion, shaved carrots, lime juice, olive oil, and vegan mayonnaise. Season with salt as desired.
Line each taco shell with 1 to 2 pieces of Bibb lettuce, then fill with the RightRice taco filling. To serve, top with your favorite taqueria-style salsa rojo and your favorite plant-based shredded cheese.
