Preheat oven to 425.
Once the shrimp has been peeled and cleaned, rinse it under cold water. Be sure to pat the shrimp really dry (if the shrimp is not dry it will steam rather than roast!).
Place the trimmed and cut beans in a bowl and toss with extra virgin olive oil, ground coriander, ground cumin, salt, freshly ground black pepper, and Cayenne pepper.
Place shrimp in another bowl with the extra virgin olive oil, lemon zest, salt, and fresh ground black pepper.
Brush roasting pan with olive oil or use a non-stick spray, then arrange beans on pan in a single layer (as much as possible). Roast beans 10 minutes. After 10 minutes, toss the beans and arrange shrimp on top and roast 8-10 minutes more or until shrimp are just done.
Squeeze the four lemon quarters over the shrimp and beans and serve immediately.
