Finely chop the red onion and green capsicum and add them to a mixing bowl along with the sweet corn.
1/4 Cup Onion, 1/4 Cup Green Capsicum (Bell Pepper / Shimla Mirch), 1/4 Cup Sweet Corn Kernels
Add the cumin powder, salt and black pepper and toss well. Season the rinsed and drained black beans in the same bowl with a little of the same spice mix.
1 Teaspoon Cumin Powder (Jeera Powder), 1/2 Teaspoon Black Pepper, 3/4 Teaspoon Salt
Preheat the oven to 375°F (190°C). Spread the tortilla chips over a lined baking tray in a single, slightly overlapping layer - wide rather than deep.
200 gm Tortilla Chips
Scatter half the grated cheese directly over the bare chips. As it melts it forms a barrier that stops the toppings from making the chips soggy, and helps everything stick.
2 Cups Mexican Cheese Blend
Scatter the seasoned vegetables evenly over the cheese.
Add the seasoned black beans, spreading them out so every part of the tray gets some.
1 Can Black Beans
Pile the remaining cheese over the top.
Arrange the sliced jalapeños over the cheese. Use fewer, or leave them out altogether, for a milder tray.
1 Jalapeño
Bake for 10 to 12 minutes, until the cheese is fully melted and bubbling and the chips at the edges are just turning golden.
Top with guacamole, sour cream and chopped coriander leaves. Serve straight away, while the cheese is still molten.
1 Cup Guacamole, 1/4 Cup Sour Cream, 2 Tablespoons Coriander Leaves (Cilantro or Dhaniya)
