What to do with leftovers for a healthy brunch? Basically beat eggs as though youre making an omelette but oven bake it so it becomes more like a Spanish tortilla

I added sweet potatoes and courgette which i part fried in coconut oil. Once cooked I kept in the fridge, taking slices out and grilling them with gruyere cheese on top till bubbling and crispy. Served with wilted spinach. Yum
