• Before starting, preheat the oven to 450°F. Wash and dry all produce.
• Cut sweet potatoes into 1/2-inch pieces. To a parchment-lined baking sheet, add sweet potatoes and 1 tbsp oil. (NOTE: For 4 servings, use 2 baking sheets, with 1 tbsp oil per sheet.) Season with salt and pepper, then toss to coat.
• Roast in the middle of the oven for 16-18 min, stirring halfway through, until tender and golden. (NOTE: For 4 servings, roast in the middle and bottom of the oven, switching baking sheet positions halfway through.)

• Peel, then cut onion into 1/4-inch slices.
• Core, then cut pepper into 1/4-inch slices.
• Peel, then mince or grate garlic.
• Thinly slice green onion.
• Zest, then juice half the lime. Cut remaining lime into wedges.

• Heat a large non-stick pan, over medium-high. When the pan is hot, add 1/2 tbsp (1 tbsp) oil, peppers, onions, garlic and half Southwest Spice Blend. Cook for 5-6 min, stirring often, until tender. Season with salt and pepper.
• Transfer to plate.
• Carefully wipe the pan clean.

• Re-heat the same pan over medium-high. When hot, add beef and remaining Southwest Spice Blend to the dry pan. Cook for 3-5 min, breaking up beef into smaller pieces, until no pink remains.** Carefully drain and discard excess fat. 
• Add tomato sauce base. Cook for 1-2 min, stirring often, until fragrant. Season with salt and pepper.

• To the pan with beef, add 1/4 cup (1/2 cup) water, veggies, half the lime zest, half the lime juice and sweet potatoes. Stir to combine.
• Cook for 3-4 min, stirring occasionally, until thickened. Season with salt and pepper.
• Add cheese. Cover the pan with a lid for 1-2 min, until cheese is melted.
• Meanwhile, to a small bowl, add sour cream, remaining lime zest and remaining lime juice. Stir to combine. Season with salt and pepper.

• Divide beef mixture and sweet potatoes between plates.
• Spoon sour cream over top and sprinkle with green onions.
• Squeeze a lime wedge over top. 

If you've opted for double beef, cook in the same way the recipe instructs you to cook the regular portion of beef. Work in batches, if necessary.
