Heat the grill to medium heat, about 350 degrees.
Halve the avocados and remove the seeds.
Skewer the garlic cloves and cherry tomatoes (no need to skewer if using Roma tomatoes).
Grill the avocado, limes, jalapenos, garlic and tomatoes until char marks form.
Chop the charred avocado into bite-sized pieces. Mince the tomatoes, garlic, and jalapeƱos.
Combine all the chopped ingredients in a bowl, next squeeze the juice from the charred limed into the bowl, using your fingers to catch the seeds.
Stir all ingredients together and add the cilantro and sea salt and pepper to taste. For extra flavor, add a little lime zest.
Chill and serve with tortilla chips. This is also excellent as a topping for fish or chicken and on salads.
