Cook the brown rice per package instructions. When pressed for time, I love using microwavable brown rice. I also like to batch cook it in my instant pot. See notes for a link to the recipe.
Add cauliflower rice to a medium-sized skillet and saute for 3-5 minutes or until tender/ the liquid is absorbed if using frozen cauliflower rice. Turn off the heat.
Add the cooked brown rice and ¾ cup of cilantro to the cauliflower rice. Stir to combine. Divide the rice mixture into 5 containers. Set aside.
In a medium-sized bowl, make the corn salsa by combining the sweet corn, remaining cilantro, onion, lime juice, chili powder, cumin, cayenne pepper, and salt and pepper to taste.
Add greek yogurt, lime juice, honey, olive oil, and salt and pepper to a mason jar. Shake vigorously to combine.
Assemble the meal prep burrito bowls. Divide the corn salsa, Sangria tomatoes, black beans, and avocado between the 5 rice-filled containers.
When ready to eat, top with the honey lime dressing and enjoy!
