Heat a 12-inch nonstick skillet over medium high heat. Brown chorizo 2 to 3 minutes, then remove from pan. Add oil, garlic, then shrimp. Season shrimp with salt and pepper and cook shrimp until pink, 2 or 3 minutes. Transfer shrimp to a cutting board and coarsely chop.
Add a drizzle of oil to the pan and a large tortilla. Cook tortilla 30 seconds, then turn. Cover 1/2 of the tortilla with a couple of handfuls of cheese. Arrange a layer of chorizo and shrimp over the cheese and fold tortilla over. Press down gently with a spatula and cook tortilla a minute or so on each side to melt cheese and crisp. Remove quesadilla to large cutting board and repeat with remaining ingredients. Cut each quesadilla into 5 wedges and transfer to plates with your spatula. Top wedges of quesadillas with Mexican Crema and serve with Pico de Gallo salsa.
