• Preheat oven to 220°C/200°C fan-forced. Drain and rinse half the black beans. Drain sweetcorn. Finely chop brown onion. • Heat a large frying pan over high heat. Cook beef mince (no need for oil!), breaking up with a spoon, until just browned, 3-4 minutes. • Reduce pan to medium-high heat. Cook black beans, onion and corn, until tender, 2-3 minutes. Lightly mash black bean mixture with a potato masher or fork. • SPICY! This spice blend is hot! Add less if you're sensitive to heat. Add Mexican Fiesta spice blend and tomato paste and cook, until fragrant, 1 minute. • Stir in the water, butter and baby spinach leaves, until wilted and combined, 1-2 minutes.

• Arrange tortillas over a lined oven tray. Divide beef and bean mixture among tortillas, spooning it onto one half of each tortilla, then top with Cheddar cheese. • Fold empty half of each tortilla over to enclose filling and press down with spatula. Brush or spray tortillas with a drizzle of olive oil and season. • Bake quesadillas until cheese has melted and tortillas are golden, 8-10 minutes. Spoon any overflowing filling and cheese back into quesadillas. TIP: Place a sheet of baking paper and a second oven tray on top of the quesadillas if they unfold during cooking.

• Meanwhile, peel and finely chop avocado. Finely chop tomato and coriander. • In a medium bowl, combine tomato, avocado coriander and a drizzle of white wine vinegar and olive oil. Season.

• Divide Mexican beef, black bean and veggie quesadillas between plates. • Top with tomato salsa. Enjoy!
