Using scissors, layer two tortillas on top of each other and cut into triangles (halve, halve, and halve again). Layer the triangles onto a baking tray and sprinkle ½ tsp salt and ½ tsp cayenne pepper over them. Bake for about five minutes in an oven at 180°C/360°F.
Heat the drained and rinsed black beans in a bowl in a microwave for about 60 seconds in a 1000w microwave. Also drain and rinse the sweet corn.
Mix the black beans with a handful chopped cherry tomatoes and ½ cup corn and arrange in a bowl. Add the baked tortillas.
Finish with taco or chipotle sauce, creme fraiche, grated cheese and some sliced avocado with a dash of salt and squeeze of lemon juice.
