Start by washing the mushrooms and cutting them into thick slices. Set them aside. Crumble the goat cheese and slice the green onions if you’re using them for garnish.
In a non-stick skillet, heat 2 teaspoons of olive oil over medium heat. Once hot, add the sliced mushrooms. Sauté for about 4-5 minutes, or until they are golden brown and tender. Season with Spike seasoning to taste, then remove the mushrooms from the skillet and set them aside.
In a mixing bowl, crack the 3 eggs and add 2 teaspoons of half and half. Use a whisk or fork to beat the mixture until it’s well combined and slightly frothy. Season with a pinch of Spike seasoning for extra flavor.
In the same skillet, reduce the heat to low and pour in the egg mixture. Let it cook undisturbed for a minute or two, allowing the edges to set. As the eggs begin to firm up, gently lift the edges with a spatula, letting any uncooked egg flow to the edges.
Once the top of the omelet is still slightly runny but mostly set, evenly distribute the sautéed mushrooms and crumbled goat cheese over half of the omelet.
Carefully fold the omelet in half using the spatula to cover the filling. Let it cook for an additional minute to warm the filling through. Slide the omelet onto a plate and garnish with thinly sliced green onions if desired.
