In a mixing bowl combine the ricotta, lemon juice, and olive oil. Set aside.
Preheat grill over medium heat. Slice baguette into 1/2-inch slices, butter one side. Grill each piece until warmed-through and slightly crisp with grill marks.
Spread the ricotta over the grilled baguette slices, top with peach wedges, mint, fresh blueberries, and drizzle with the balsamic glaze. Serve immediately and enjoy!
