Heat the oven: Preheat to 425°F (220°C).
Line a large baking sheet with parchment for easy cleanup.
Prep the sweet potatoes: Toss the cubes with olive oil, smoked paprika, garlic powder, cumin, salt, and pepper. Spread in a single layer on the sheet.
Roast for color: Roast 20–25 minutes, flipping once halfway. They’re done when edges are browned and centers are tender.
Keep warm.
Season the steak: Pat dry with paper towels. Rub with olive oil, then sprinkle on salt, pepper, chili powder, and garlic powder. Press seasonings in so they adhere.
Heat the pan: Use a cast-iron or heavy skillet over medium-high heat until very hot.
You want a strong sear for flavor.
Sear the steak: Add the steak and sear 3–5 minutes per side for medium-rare, depending on thickness. For skirt steak, it may be closer to 3 minutes per side. Avoid moving it too much.
Rest and slice: Transfer steak to a cutting board and rest 5–10 minutes.
Slice thinly against the grain for tenderness.
Make the sauce: Stir yogurt, mayo, lime juice, grated garlic, and salt in a small bowl. Thin with water to drizzle consistency. Taste and adjust lime or salt.
Prep the base: Warm cooked brown rice or quinoa if chilled.
Toss greens lightly with a squeeze of lime and a pinch of salt to brighten.
Assemble bowls: Divide greens and grains among bowls. Add roasted sweet potatoes, sliced bell pepper, red onion, avocado, and steak.
Finish and serve: Drizzle with the creamy garlic-lime sauce. Top with cilantro and a squeeze of fresh lime.
Serve right away.
