Here's a great idea to use up some bits of baguette that's going stale and also a last-minute easy recipe for an apéritif:
What you need:
Baguette slices (about 1 cm thick and cut as rounds)
tomatoes sliced thin
fresh basil leaves
olive oil or pesto sauce
Place the slices of baguette on a baking sheet. Place a slice of tomato on each, then the cheese (just enough to cover when it melts) and finish with a dab of pesto sauce (optional) or just a basil leaf each and a drop of olive oil. Place in a hot oven until toasted. Serve warm.
