2 cups (500 mL)thinly sliced white or cremini mushrooms
1 tbsp (15 mL)balsamic vinegar
1/3 cup (75 mL)chopped fresh parsley
1/8 tsp (0.5 mL)pepper
Step 1 Preheat broiler.
Step 2 Whisk eggs, parsley and pepper in medium bowl; set aside.
Step 3 Heat oil in 8-inch (20cm) non-stick ovenproof skillet over medium heat. Add onions; cook, stirring frequently, until soft. Add mushrooms and balsamic vinegar; cook, stirring frequently, until mushrooms are soft.
Step 4 Pour in egg mixture. As eggs set around edge of skillet, with spatula, gently lift cooked portions to allow uncooked egg to flow underneath. Cook until bottom is set and top is almost set, about 8 to 10 minutes.
Step 5 Place skillet under preheated broiler until eggs are set, 2 to 3 minutes.
