Heat the oven broiler. Move the oven rack so it is a couple inches under the broiler.
In a bowl, whisk together the Sriracha, olive oil, garlic, vinegar, honey, salt, and pepper. Toss in the shrimp to coat. Spread the shrimp on a bake sheet. Broil 2-3 minutes or until just cooked through.
To assemble the appetizers, lay out the crackers. Spread guacamole on each. Top with a shrimp, then a little dollop of pineapple preserves. Garnish with a couple snipped tips of chive. Yields: 15-20 bites.
