2 lb unpeeled baby red potatoes, halved (about 6 cups)
1 jalapeno pepper, finely chopped (with seeds)
1 tsp ground cumin
1 tsp smoked paprika
1 tsp salt
1 cup chopped fresh cilantro
2 tbsp fresh lime juice
1 tsp grated lime peel
Preheat grill on medium heat for 10 - 15 minutes.
Combine potatoes, jalapeno pepper, olive oil, cumin, paprika and salt in a bowl.
Place potato mixture in center of a large piece of heavy-duty foil. Bring edges of foil together to form a packet; close all edges with tight double folds.
Cook, turning packet over after 15 minutes, until potatoes are tender, about 30 - 35 minutes. Remove from heat.
Open packet and transfer potato mixture to a heatproof bowl. Add cilantro, lime juice and lime peel; toss to coat.
