Shrimp and Chorizo Sandwich

Directions

1. Bring a medium saucepan filled with heavily salted water to a boil. Add the shrimp and turn off the heat. Let the shrimp rest in the water for 3 minutes, then cut into one shrimp to see if it's cooked -- it should be just cooked and still springy. If they're cooked, drain and rinse the shrimp under cold water for 15 seconds (to cool them just slightly). If not, let them continue poaching until cooked through. Slice the cooked shrimp into 1/4-inch pieces.
2. Meanwhile, cut the chorizo -- I like to cut it into quarters lengthwise, and then crosswise into 1/8-inch slices.
3. Make the aioli: in a bowl, whisk together the mayonnaise, garlic, and lemon (feel free to add more lemon, and salt, if desired).
4. In a large mixing bowl, combine the shrimp, chorizo, scallions, and half the aioli. Fold together. Taste and adjust seasoning, adding more aioli as needed.
5. Slice open the rolls. Spoon on the shrimp salad. Top with arugula and the top halves of the rolls. Pack up in your lunch box!
