Quesadillas au chou frisé et aux haricots noirs

Combine sour cream and 1/2 tsp Mexican seasoning (dbl for 4 ppl) in a small bowl. Set aside. Combine tomatoes, cilantro, half the onions, half the lime zest, half the lime juice and 1 tbsp oil (dbl for 4 ppl) in another medium bowl. Season with salt and pepper. Set aside.

Heat a large non-stick pan over medium-high heat. When hot, add 1 tbsp oil (dbl for 4 ppl), then remaining onions. Cook, stirring occasionally, until softened, 2-3 min. Add kale and 2 tbsp water (dbl for 4 ppl). Cook, stirring often, until kale is tender, 5-6 min.

Add garlic, beans and remaining Mexican seasoning to the same pan. Cook, stirring often, until garlic is fragrant and beans are warmed through, 1-2 min. Stir in remaining lime zest and remaining lime juice. Transfer bean mixture back into the same medium bowl. Season with salt and pepper. Set aside. Carefully wipe the pan clean.

Arrange tortillas on a clean surface. Divide bean mixture over one half of each tortilla. Sprinkle with cheese. Fold the other side of tortillas in half over filling. Heat the same pan over medium heat. When hot, add 1/2 tbsp oil, then 3 quesadillas at a time. Cook, until golden-brown, 1-2 min per side. Repeat with remaining quesadillas.
