This is one of my favorite sweet potato dishes!

4 large organic sweet potatoes, peeled, diced in 1 inch cubes
2 medium red peppers- diced medium
1 bunch scallions- sliced thin, diagonally
1 bunch cilantro- chopped coarsely
1 1/2 Tablespoons Dijon mustard
salt and pepper to taste
1 teaspoon cumin
3/4 teaspoon smoked paprika
1 teaspoon fresh ginger- grated with ginger grater, use juice also
2 limes- juiced, use zest from one in salad (use microplaner for this)

1)  Toss potatoes in butter, roast in 374 degree oven until edges are browned

2)  Toss with all other ingredients, let sit about 30 minutes before serving.
