Directions
1. Toss shrimp, garlic, oil, and lime juice in a large baking dish. Cover, and refrigerate, turning occasionally, for 30 minutes. Meanwhile, soak 8 wooden skewers in water.
2. Preheat grill to medium-high. Thread the shrimp, slices of chorizo and sliced poblano pepper onto each skewer, alternating pieces. Season with salt. Grill until shrimp are opaque and chorizo is slightly softened, about 3 minutes per side.
3. Arrange avocados on a platter. Squeeze lime wedges over avocados, and season with salt and pepper. Serve with shrimp-and-chorizo skewers.
