Preheat oven to broil.
Lightly oil bread slices with olive oil and place them on a baking sheet. Place in oven and toast until golden brown and crisp.
While toast is still warm, rub 1 side of each slice with the fresh garlic. Place 2 sardine fillets, silver skin side facing up, on each toast and put back on the baking sheet. Season with salt and pepper.
Bake for 4 to 6 minutes. Remove tray from oven and garnish with just a squeeze of lemon juice and chopped parsley. Serve immediately.
