Cut baguette into 32 slices, about 1/2 in. thick; place on ungreased baking sheets. Brush with oil. Broil 6-8 in. from the heat for 1-2 minutes or until lightly toasted.
In a small bowl, combine the strawberries, peaches and mint. Spread each slice of bread with cheese; top with fruit mixture. Broil for 1-2 minutes or until cheese is slightly melted. Serve immediately.
