Using a large pan, heat the avocado oil over medium heat. Add the tortillas one by one and cook for about 2 minutes on each side or until the tortilla starts to crisp. Set aside and repeat with all of the tortillas and set aside.
Prepare the avocado mash by combining the avocado with salt, pepper, lime juice, and minced garlic.
Assemble the tostadas by layering on the mashed avocado, then the shredded chicken, red onion, mango, and cilantro lime dressing. Serve fresh.
Notes
You can use other varieties of Siete brand tortillas, or other grain-free tortillas like homemade cassava tortillas for AIP. The trick is to just get them nice and crispy, so each of the different varieties of tortillas will vary a bit with cook times, but as long as you keep a close eye on it you can make it work.All nutrition facts are estimated and will vary.
