Heat a large skillet over medium-high heat. Add the shrimp in a single layer and sear for 1–2 minutes per side, just until pink and opaque. Remove from the heat immediately to prevent overcooking.
1 tablespoon olive oil
Warm the tortillas in a hot, dry skillet until pliable, or microwave them in a covered stack for 20–30 seconds. If using corn tortillas, layer two together for each taco to keep them from tearing.
16 small corn tortillas
Add a scoop of slaw to each tortilla stack, top with a few shrimp, sliced avocado, jalapeños (if using), and a drizzle of the cilantro-lime cream sauce.
Serve immediately with lime wedges.
