If using frozen precooked shrimp, place the frozen shrimp in a colander and run cold water over them for five minutes or until all are defrosted. Let shrimp drain in colander while you prepare the vegetables. If using uncooked shrimp, peel and devain them, place them in a bowl and set them aside.

Scrub the baby potatoes under cold water, dry them, place them on a cutting board and cut each one in half.

Place the potatoes and green beans in a microwave safe bowl. Add 2 tbsp of water. Cover bowl with a plate and microwave on high for 4 minutes.

While vegetables are cooking in microwave, juice and zest the lemon or lime into a small bowl.

When the potatoes and green beans are done, drain the water out of the bowl. Lay out the foil sheets. Place the drained green beans and potatoes in the center of the foil. Pile on the shrimp and one half or both halves of the corn. Drizzle the all the food with the lime dressing.

Bring two opposite long sides of the foil up to meet in the center; fold edges over twice to make a tight seal. Double fold remaining open sides on the ends to seal packet tightly.

Place the packet on a cookie sheet and place in a 350º oven for for 15 - 20 minutes depending on the size of your shrimp. Open up the packet to see if the potatoes and beans are done. If not, seal up the packet and return to oven for 5 to 10 mor minutes.

To serve, give each person a packet or open the packets on individual plates and then serve with extra melted butter and slices of lime. Pass a basket of crusty french bread.
