Prepare the Tortillas:
Heat olive oil in a frying pan over medium heat. Once hot, fry one tortilla at a time until golden brown and crispy, about 1-2 minutes per side. Remove from the pan and place on a paper towel to drain excess oil.
Shred the Chicken:
If not already done, shred your cooked chicken into bite-sized pieces. You can use a rotisserie chicken for convenience!
Assemble the Tostadas:
Place a crispy tortilla on a serving plate. Layer with shredded chicken, then top with a generous handful of shredded lettuce, diced tomatoes, and shredded cheese.
Add the Extras:
Top with sliced avocado, a drizzle of sour cream, and a spoonful of salsa or pico de gallo if you like it spicy!
Garnish and Serve:
Sprinkle chopped cilantro over the top and serve with lime wedges on the side. Enjoy your scrumptious Chicken Tostadas!
