Pre-heat the oven to 425 degrees F and line a baking sheet with parchment paper.
Cut cauliflower into florets and then "chip" sized pieces and arrange them on a single layer on the baking sheet. Drizzle cauliflower pieces with oil and season with cumin, paprika, chili powder, salt and pepper.
Bake for 20-25 minutes.
Remove cauliflower from oven, evenly spread the shredded cheese, beans, corn or corn salsa, and pickled jalapeno. Place back in the oven and bake for another 5-8 minutes or until the cheese is melted (keep an eye on them so they don't burn!)
Top with diced avocado, lime juice and fresh cilantro. Serve immediately!
