1. Preheat oven to 400°F (convection if you have it) and drizzle 2 Tbsp avocado oil on a baking sheet.
2. Coat tortillas in oil on both sides, sprinkle with some salt, and bake for 7 minutes on the first side, flip and bake for 3-4 more minutes until golden brown and crispy (if you are not using convection you may have to cook a bit longer).
3. Mix together the ingredients for the dressing and set aside.
4. Place ingredients for the ceviche in a bowl and pour the dressing on top; mix to evenly coat the veggies and serve on top of the tostadas with 1 tsp cotija cheese sprinkled on each one - enjoy!
