Mix all of the ingredients for the marinated salmon and let rest for 30 minutes.
Sour Cream
Beat the cream with the lemon juice and zest until it thickens and mounds.
Prep and Plating:
Place an oven rack in the middle position. Preheat the oven to 350º F. Baste the slices of Whole Oat Bread with a little bit of oil, season with salt and pepper, and place them on a baking sheet.
Cook the bread slices in the oven until they are golden, about 8 to 10 minutes. Let rest.
Wash and cut the kale. Season with salt and pepper; let rest.
Wash and peel the cucumbers; cut the flesh into 1.5 cm cubes.
Divide the salmon equally between the 4 slices of bread; top with the cucumbers, kale, and a big dollop of sour cream.
