Whisk sauce ingredients until smooth.
Toss romaine, pepperoncini, parmesan, and about half of the Caesar sauce until well-combined. (For the remaining sauce – whisk it with 1-2 tablespoons of water to make it smoother for dunking.)
Mix the seasoning into the ground chicken. Place your tortillas on a large cutting board or tray; spread each tortilla with some of the ground chicken mixture, pushing it all the way to the edges or even slightly past.
Heat a thin layer of oil over medium heat (2 tablespoons or more will give you the best crispy crust). Working in batches, place the tortilla chicken-side down and press down with a spatula for 15-30 seconds. Cook for another 2-3 minutes until the chicken is browned and fully cooked. Flip to the other side for another minute to get a bit of crisping on the back side of the tortilla.
Remove tacos from skillet and fold in half (the tortilla may crackle a bit when you fold them – that’s fine!). If needed, place on a baking sheet and pop in a warm oven until you’re ready to serve. When you’re ready to eat, stuff the Caesar salad inside the tacos!
Serve alongside a dish of the remaining Caesar sauce for dipping.
