Preheat and prep the potatoes: Heat the oven to 425°F (220°C). Toss sweet potato cubes with 1 tablespoon olive oil, a big pinch of salt, and black pepper.
Spread on a sheet pan in a single layer. Roast 20–25 minutes, flipping once, until tender and caramelized at the edges.
Cook your grains: While the potatoes roast, cook rice or quinoa according to package directions. Fluff and set aside.
If using cauliflower rice, sauté in a little oil with salt until just tender.
Brown the chicken: Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add ground chicken and a pinch of salt. Cook, breaking it up with a spatula, until lightly browned and no longer pink, about 5–6 minutes.
Don’t stir constantly—let it sear so you get some color.
Add aromatics: Reduce heat to medium. Add diced onion and bell pepper. Cook 3–4 minutes until softened.
Stir in garlic and cook 30 seconds until fragrant.
Season and sauce: Stir in tomato paste, chili powder, smoked paprika, cumin, cinnamon, and red pepper flakes if using. Cook 1 minute to toast the spices. Add soy sauce, vinegar or lime, and honey.
Stir to coat and simmer 1–2 minutes. Taste and adjust salt, sweetness, or acidity as needed.
Add greens: Fold in spinach or kale. Cook until just wilted, 1–2 minutes.
Turn off the heat.
Assemble the bowls: Add a scoop of grains to each bowl. Top with roasted sweet potatoes and a generous spoonful of the seasoned ground chicken mixture.
Finish with toppings: Add a dollop of Greek yogurt or sour cream, sprinkle with cilantro or green onions, and add avocado if you like. Serve with lime wedges.
Enjoy right away.
