For the Chicken: In a large bowl, whisk together the olive oil, garlic, lime zest, lime juice, chopped cilantro, Chili Lime seasoning, and kosher salt. Add the chicken thighs and toss to evenly coat. Let the chicken marinate at room temperature for 15 minutes or in the fridge for up to 2 hours.
Heat a large nonstick skillet over medium-high heat. Working in batches, cook the chicken for about 6 minutes per side, until cooked through and lightly charred. Let it rest for 5 minutes, then slice or shred.
Make the Crispy Tortilla Strips: Cut corn tortillas into thin strips. Heat a shallow layer of oil in a skillet and fry the strips until golden and crispy. Transfer to a paper towel–lined plate and season with salt while hot.
Assemble the Salad: Layer the shredded romaine, bacon, avocado, Colby Jack, and cilantro in a large bowl or on a platter. Top with the chicken and crispy tortilla strips. Serve with lime wedges and the homemade vinaigrette below.
Make the Chili Lime Vinaigrette: Combine all vinaigrette ingredients in a blender or small food processor and blend until smooth. Taste and adjust seasoning as needed. Store any extra in a sealed jar in the fridge for up to a week—just give it a good shake before using.
