Avocado toast the you need a fork for. When I make a croque monsieur I only need a little of the bechamel so I divide the rest into single portions and put them in ziploc bags and freeze it. It reheats beautifully. I defrosted it in a bowl of hot water and warmed it up in a sauce pan. This one is a smoked gruyere bechamel. We have a toasted slice of brioche, mashed avocado with lemon and salt, soft scrambled eggs with yogurt and chives, topped with bechamel.
