Before starting, preheat the oven to 450°F.Wash and dry all produce. Core, then cut pepper into 1/4-inch slices. Peel, then cut onion into 1/4-inch slices. Add peppers, three-quarters of the onions, half the Mexican Seasoning and 1 tbsp (2 tbsp) oil to an unlined baking sheet. Season with salt and pepper, then toss to combine. Roast in the middle of the oven, stirring halfway through, until tender, 12-14 min.

Meanwhile, zest, then juice half the lime (whole lime for 4 ppl). Cut any remaining lime into wedges. Cut tomatoes into 1/4-inch pieces. Finely chop remaining onions. Add tomatoes, chopped onions, 1/2 tsp (1 tsp) sugar, 1/2 tbsp (1 tbsp) lime juice and 1/2 tbsp (1 tbsp) oil to a small bowl. Season with salt and pepper, then stir to combine. Set aside.

Add sour cream and lime zest to another small bowl. Season with salt and pepper, then stir to combine. Set aside.

Heat a large non-stick pan over medium-high heat. When hot, add 1/2 tbsp (1 tbsp) oil, then beef. Cook, breaking up beef into smaller pieces, until no pink remains, 4-5 min.** Carefully drain and discard excess fat. Add remaining Mexican Seasoning. Cook, stirring often, until fragrant, 1 min. Season with pepper, to taste.

Meanwhile, wrap tortillas in foil, then place in the top of the oven until warm, 4-5 min. (TIP: You can skip this step if you don't want to warm tortillas!)

Top tortillas with beef and veggies, then spoon salsa fresca over top. Dollop with lime crema and sprinkle with cheese. Squeeze a lime wedge over top, if desired.
