Heat the grill, grill plate or cast-iron grill pan over medium-high heat (for the LeMax level 9). Once hot, lightly coat with a drizzle of oil.
Grill the chicken breast for 3-5 minutes on each side, until golden-brown and fully cooked (time will vary depending on thickness of the pieces; for 2cm thickness, plan about 5-6 minutes per side. Thinner cutlets cook in about 3 minutes per side).
NOTE: If using a grill pan and working in batches, transfer cooked chicken to a platter and cover with tinfoil or place in a low heated oven to keep warm. Continue grilling the remaining chicken, adding more oil if the pan gets too dry.
Remove the chicken from the grill, and serve immediate topped with avocado salsa on the top, an extra wedge of lime for squeezing on top and your choice of side dishes. Enjoy!
