Arrange slices of Grison Beef on 8 slices of bread. Cover with thin slices of camembert. Top with 4 fresh slices of tomato and arugula. Cover with the remaining 8 slices of bread.
Preheat oven to 400°. Bake 15-18 min on a paper-lined plate. When ready, top with a thin slice of camembert and bake again for a few minutes.
Serve with a salad of red and yellow cherry tomatoes, seasoned with shallots.
Toast the bread longer for more crunch. You may use a toaster for a crispier texture.
If you cannot find bresaola at your local store, use roast beef, preferably cured with black pepper.
