Preheat the BBQ grill to medium-high heat, ensuring it reaches a temperature of at least 375°F.
In a mixing bowl, whisk together ¼ cup of extra-virgin olive oil, 4 tablespoons of freshly squeezed lemon juice (equivalent to the juice from 1 lemon), and the finely grated zest of 2 lemons to create a marinade.
4 tablespoon lemon juice, 2 tablespoon lemon zest, ¼ cup extra-virgin olive oil
Reserve ¼ cup of marinade and set aside. Thread each of the 20 chicken breast tenders onto its own small wooden skewer and dip each one into the remaining three-quarters of the marinade to coat.
2 lb chicken breast tenders
Generously season the coated chicken tenders with black pepper and 1 teaspoon of sea salt, increasing the amount to taste.
1 teaspoon sea salt, 1 teaspoon black pepper
On the preheated grill, place the skewers and cook, covered, for approximately 3 minutes on each side until well browned and beginning to char in spots.
When done, transfer the chicken tender skewers to a serving platter and then drizzle the reserved marinade over the chicken. Serve hot.
