This easy frittata is baked in a skillet with hearty kale, fragrant garlic and Grana-style cheese.
1 bunch Lacinato kale, cut crosswise into wide strips
2 cups purple potatoes, washed and cut into thin coins
1 yellow onion, peeled and diced
¼ cup olive oil
3 garlic cloves, sliced paper thin
8 large eggs
½ cup Grana-style cheese, grated
Sea salt and fresh ground pepper
1. Heat olive oil in a broiler-proof nonstick skillet over medium-low heat, then add potato coins and diced onions. Cook, stirring carefully and occasionally, until the onions brown and the potatoes are tender. This should take about 15 to 20 minutes. Toss in the kale and garlic and cook for five minutes, stirring occasionally. Turn off the heat and season with salt and pepper.
2. Preheat oven broiler, positioning oven rack about 4-6 inches from heat.
3. In a medium bowl, whisk together eggs, Grana cheese and an additional ½ teaspoon salt. Slowly pour egg mixture over the vegetables. Cook eggs over medium-low heat without stirring for 8 minutes, or until almost set.
4. Transfer skillet to broiler and broil for 2-3 minutes, or until top of frittata is browned. (Check often to make sure it does not burn.) Remove and let sit 3-4 minutes before slicing into wedges and serving.
