Cheesy Shiitake Arugula Omelette

• 1 tbsp (15 mL) unsalted butter
• 1 cup (250 mL) shiitake mushrooms
• Pinch of salt
• Pinch of black pepper
• 3 eggs, beaten
• 1/3 cup (75 mL) baby arugula
• 1/3 cup (75 mL) grated cheese, such as Gouda, Cheddar or Fontina

• Melt the butter in a non-stick pan over medium heat. Add the mushrooms and sauté until beginning to get crisp around the edges (4 to 5 minutes). Transfer the mushrooms to a small dish and set aside.
• Pour the beaten eggs into the pan. Keeping the heat on medium, allow the eggs to cook undisturbed until just a little wet on top (3 to 4 minutes).
• Sprinkle the cheese over the eggs. Arrange the arugula and mushrooms on just one side of the eggs. Continue cooking another minute or so just until the eggs have set. Gently flap over the eggs to cover the mushroom side of the omelette. Serve hot.
