1 lb small peruvian purple potatoes (may substitute small Yukon Gold potatoes)
6 green onions
3 tablespoons sherry wine vinegar
2 tablespoons extra virgin olive oil
1 teaspoon ground cumin
12 teaspoon fresh ground black pepper
12 cup fresh cilantro (leaves from about 4 to 6 stems)
8 cups mesclun
Instructions
In a small bowl, combine fresh lime juice, garlic, 1/2 teaspoon salt and chipotle or chili powder; mix well.
Rub mixture all over steak; refrigerate while potatoes are cooked.
In a large pot, cover potatoes with water and boil over high heat until just tender, about 15 minutes; drain and let cook about 5 minutes and cut into halves or quarters.
Meanwhile, trim radishes and cut into thin slices.
Cut green onions into thin slices.
Chop the cilantro to yield about 1/2 cup.
In a large bowl, combine warm potatoes with the radishes, green onions, and cilantro.
Now grill the steak over medium high heat on a grill pan or outdoor grill for 8 to 10 minutes, then turn and cook another 8 minutes until it reaches 140 degrees F on a meat thermometer and is nicely browned.
Let rest about 5 minutes before slicing into 1/4 inch slices.
While the steak is resting, whisk together the vinegar, oil, cumin, pepper and 1/2 teaspoon salt; add to potatoes and toss to coat.
Add the steak and any juices that may have accumulated; toss.
Arrange salad greens on individual serving plates.
Top each with an even amount of the steak and potato mixture.
