In a large non-stick skillet, warm the olive oil over medium heat. Once the oil is shimmering, add the riced cauliflower, diced bell pepper, and chopped red onion. Sauté for approximately 3-4 minutes, stirring occasionally, until the vegetables are tender and fragrant.
Create space in the skillet by pushing the sautéed veggies to one side. Crack the eggs directly into the cleared area and gently break the yolks with a spatula. Scramble the eggs until they are cooked through and fully set, which should take about 2-3 minutes.
Incorporate the black beans, cumin, salt, and pepper into the scrambled eggs. Stir the mixture well to ensure everything is evenly combined. Cook for an additional minute to warm the black beans through.
Remove the skillet from heat and sprinkle shredded cheese over the entire mixture. Cover briefly to allow the cheese to melt slightly from the residual heat.
To serve, carefully spoon the burrito bowl mixture into individual bowls. Garnish each bowl with a generous topping of fresh cilantro and arranged avocado slices. Add hot sauce on top if desired for an extra punch.
Notes
Serve warm with a sprig of cilantro and a slice of lime for added zest.
