In a bowl, mix ricotta, dill, lemon zest, lemon juice, salt, and pepper until smooth but still fluffy.
Chill briefly while you prepare the toasts.
Brush bread slices lightly with olive oil. Toast at 375°F for 6–8 minutes until golden. While warm, sprinkle each with everything bagel seasoning so it sticks.
Spread about 1½–2 Tbsp dill ricotta on each toast. Top with salmon, a few capers, and red onion slivers. Finish with extra dill for garnish.
Enjoy!
