Using a large, deep skillet heat the avocado oil over medium heat. Add the green plantain slices in small batches, being careful to not overcrowd the pan. Lightly salt. Cook for 2-3 minutes on each side or until softened.
Use tongs to carefully remove the plantain slices from the heat. Smash the plantains down with the bottom of a glass cup, flattening them thin. Add back to the oil, (adding more if needed) and crisp for 2-3 minutes on each side or until crispy. Repeat with all of the plantains and set aside on a large serving plate (or two-three small plates) when done.
For the nachos
To make the avocado topping, add all of the ingredients to a blender and blend until smooth, adding more avocado oil if needed. Set aside.
Top the tostones with the remainder of the toppings and drizzle with avocado topping. Serve fresh.
