Description
Going into the Coronavirus lockdown this year, I stored some vegetables in my freezer, just in case! Today I thought it is time to start using them up.
I usually make Spinach and Mushroom Gratin but I decided to experiment and it came out pretty good so I would like to share it with you here. It just goes to show that by learning some basics in cooking you can apply it to other types of food.
By the way, this is also an excellent way to tempt children or grown-ups who don't like vegetables to enjoy them!
