Preheat a conventional oven to 450°f / 230°c (or 420°f / 215°c if you're using a convection oven).
Place tortilla chips into a medium-sized rectangular baking dish approximately three layers deep.
Spoon the refried beans over the chips first and then place the chicken cubes (with the juice) over the refried beans and chips.
Add two more layers of chips and then generously top with grated white and yellow cheddar.
Place the baking dish in the oven and heat for 5 to 10 minutes checking frequently until the cheese is melted and just starting to brown on the edges. Remove from the oven and place on a heat-proof surface.
Add the remaining ingredients in layers, starting with the guacamole, then the diced tomato, diced onion and pickled jalapeño. Using a squeeze bottle, add the Mexican crema in an artistic criss-cross pattern. Optionally garnish with chopped cilantro and serve with a spoon or spatula.
Notes
Modify the ingredient amounts to your taste. Assuming that you don't overcook the nachos, you can't mess up this recipe!
You can omit the chicken or replace it with steak.
It's best to use homemade guacamole in this nachos recipe.
