Make dressing/marinade.
Whisk together olive oil, red pepper flakes, lime juice, garlic and cumin until emulsified.
Place chicken breasts in a large resealable plastic bag.
Pour about half of the lime dressing over the chicken, close bag and toss chicken to coat.
Marinate 15.
Meanwhile, heat 2 tablespoons vegetable oil in a medium skillet over medium heat.
Cut tortillas in half, then slice the halves into ½”-thick strips.
When the oil is shimmering and very hot, add the strips to the oil.
Fry until crispy, about 2 per side.
Drain on paper towels and season immediately with salt.
In a separate skillet, heat remaining vegetable oil over medium-high heat.
Add chicken and cook for 6-8 per side, until the chicken is cooked through.
Let rest for 10 before slicing.
Assemble salad.
Toss remaining ingredients in a large serving bowl.
Top with cooked chicken and crispy tortilla strips then toss with dressing.
