For the chicken, combine marinade ingredients in large plastic bag then add chicken and chill 1 hour or up to overnight.
For the mojo, over medium-high heat, saute garlic in 2 tablespoons olive oil until golden brown, about 2-3 minutes. Add cilantro or parsley, mint, chilies, sherry vinegar, agave and salt to a food processor. Pulse until finely chopped. Remove to bowl and stir in 1/2 cup EVOO; adjust salt to taste.
Prepare an outdoor grill or two-burner indoor grill pan with one side over low heat; the opposite side over medium-high heat. Cook chicken 20 minutes over indirect or low heat, turning occasionally, then finish 3-5 minutes over higher heat to caramelize and mark evenly.
Serve chicken with green mojo sauce drizzled over the top and pass lime wedges at table.
