Step 1: Make the Dressing
In a mixing bowl, combine olive oil, parmesan cheese, apple cider vinegar, hot sauce, garlic, Dijon mustard, salt, and pepper. Whisk vigorously for 1–2 minutes until fully emulsified and creamy. Taste and adjust spice or acidity as needed.
Step 2: Prepare the Chicken
Pat chicken breasts dry with paper towels. Rub with olive oil and season both sides with salt and pepper. Drying the chicken ensures proper searing and grill marks.
Step 3: Grill the Chicken
Preheat grill or grill pan to medium-high heat. Grill chicken for 8–10 minutes per side, or until the internal temperature reaches 165°F (74°C). Let rest for 5 minutes before slicing.
Step 4: Serve
Slice the chicken and drizzle with the dressing, or toss lightly to coat. Garnish with fresh herbs like parsley or cilantro if desired. Serve immediately.
