Step 1

Preheat oven to 425 degrees. Line a baking sheet with foil then place sweet potatoes on foil. Drizzle with 3 Tbsp olive oil and toss to evenly coat.

Step 2

Sprinkle evenly with cumin, paprika, coriander, cayenne pepper and season lightly with salt and pepper to taste then toss to evenly coat. Bake in preheated oven 15 - 20 minutes until tender, removing from oven and tossing once halfway through baking.

Step 3

Meanwhile, in a large skillet, heat remaining 1 Tbsp olive oil over medium-high heat. Once hot add onion and saute until caramelized (golden brown on edges and tender), about 5 - 6 minutes, adding in garlic during last 30 seconds of sauteing.

Step 4

Reduce heat to medium-low, add in drained black beans, corn, honey and lime juice. Heat until warmed through. Toss in roasted sweet potatoes and cilantro. Serve over warm tortillas with desired toppings.
