Slice the baguette, toast the slices lightly and put them on a baking tray on top of a bakingsheet.
Prepare a mixture of olive oil, crushed garlic, salt & pepper and spread a little on each slice of toast.
Chop up the mussels roughly (you can used canned ones if you like) and add a portion to each of the toasts.
Top off with freshly grated parmesan cheese (or mozerella for a lighter taste) and grill/bake until golden.
Serve right out of the oven!
