Drizzle cheese with a touch of olive oil. Place cheese on the grill for 45 seconds. Flip the cheese and grill for another 45 seconds. Transfer cheese to a small round baking dish. Sprinkle with oregano and crushed red pepper. Serve immediately, using small knives to spread the cheese mixture onto bread slices. Drizzle Chimichurri sauce over.
Chimichurri Sauce: Place garlic, aji molido, parsley, chili flakes, and salt in the bowl of a food processor and puree until well ground. With the machine running, add vinegar and slowly pour in oil; process until emulsified. Transfer to a deep jar. The sauce can be kept, covered, for up to 3 months in the refrigerator.
