Sauté the spinach and mushrooms
Heat a small, non-stick skillet over medium-high heat. Add a bit of oil, then add the sliced mushrooms and a pinch of salt. Sauté the mushrooms until softened and starting to brown. Add a few handfuls of spinach and cook until the spinach is softened. Season to taste with salt and pepper. Set aside.
Cook the JUST Egg
If using JUST Egg, scramble (like an egg) in non-stick skillet over medium heat with a bit of oil. Stir occasionally, letting it set into large curds that will hold together nicely in a sandwich. Once the liquid is cooked through, remove from the heat.
If using JUST Egg Folded, heat up in a toaster, oven, skillet or microwave according to the directions on the box.
Assemble the sandwiches
Split the croissants in half (option to toast) and layer a slice of cheese on the bottom halves. Top the cheese with cooked JUST Egg, spinach and mushrooms. Add a dash of hot sauce or cracked black pepper, if desired.
Close the sandwich and enjoy immediately – or take it to-go.
