Toast the French bread. Whip the ricotta cheese with the chopped chives, and dill. Stir in the juice and zest from one lemon with the kosher salt and pepper. Spread the toast with ¼ cup of the ricotta mixture per slice, then top with egg slices and smoked salmon. Sprinkle with more herbs, minced onion, and a little more pepper, if desired. Finish with a squeeze of lemon juice and serve.
