This taco bowl features a hearty base of roasted white potatoes and fluffy cauliflower rice topped with savory ground beef, mushrooms, and red bell peppers. Fresh lime juice and cilantro brighten every bite, while creamy avocado adds richness and balance. It’s a satisfying, veggie-packed, high-fiber twist on classic taco flavors that’s easy enough for weeknights and perfect for build-your-own bowls.
Preheat the oven to 425 degrees F. Toss diced potatoes with 1 1/2 tsp olive oil, 1/4 tsp salt, and 1/8 tsp black pepper. Spread in a single layer on a baking sheet and roast for 20–25 minutes, stirring once halfway through, until tender and lightly browned.
In the same skillet, heat the remaining 1 1/2 tsp olive oil over medium heat. Add ground beef, chopped mushrooms, and diced red bell pepper. Cook for 8–10 minutes, breaking apart the beef, until meat is fully cooked and vegetables are tender.
Stir in chili powder, cumin, smoked paprika, garlic powder, onion powder, remaining 1/4 tsp salt, and 1/4 tsp black pepper. Cook for 1–2 minutes until fragrant. Add the tomato sauce and water and bring to a simmer. Bring to a boil then reduce heat and simmer for 5-7 minutes, until the liquid is reduced. Remove from heat.
While the beef mixture is simmering, heat cauliflower rice in a large nonstick skillet over medium heat for 3–4 minutes, stirring occasionally until heated through. Add the cilantro and lime juice and mix together. Keep warm until ready to serve.
Divide the cauliflower rice evenly among four bowls. Top each bowl evenly with roasted potatoes, beef-mushroom-pepper mixture, two tomatoes, and 1/4 of a sliced avocado.
