In a medium bowl, combine the shrimp with the olive oil, garlic and oregano, parsley, red pepper flakes, and salt and pepper. Let marinate 1 hour. Place the canola oil in a small saucepan and heat to 350 degrees, add the garlic slices and fry until lightly golden brown. Remove with a slotted spoon and drain on paper towels. Preheat grill. Remove shrimp from marinade and grill for 2 to 3 minutes on each side until cooked through. Place on a platter and top with garlic chips.
