For the Quick Pickles: Pour the water and sugar in a large microwave-safe bowl. Microwave on high until the water comes to a boil, usually 3 minutes. Stir to dissolve the sugar; then add the vinegar and salt. Slice the cucumber very thin and stir the slices into the pickling liquid. Set aside for as long as possible.
For the Herbed Cream Cheese: Place the cream cheese, garlic, dill, and lemon zest in a mixing bowl. Smash and stir until well combined. Salt and pepper to taste. Set aside.
Twist the Thomas’ Everything Bagels to separate the halves, then lay them cut-side-up on baking sheets. Toast in the oven for 5-8 minutes.
To Serve: Place the bagel halves on plates. Smear the top of each bagel with herbed cream cheese. Drain the pickles. Then layer each bagel with thinly sliced smoked trout and quick pickles. Garnish with extra dill and cracked pepper if desired.
