Begin by slicing the salmon into thin, even pieces, about 1/4 inch thick. Arrange the slices on a serving platter.
In a small bowl, whisk together the orange juice, lemon juice, olive oil, dill, parsley, sea salt, and black pepper until well combined.
Drizzle the citrus dressing over the salmon slices, ensuring they are evenly coated.
Allow the salmon to marinate in the refrigerator for about 15-20 minutes to absorb the flavors.
Just before serving, arrange the avocado slices around the salmon and garnish with microgreens or edible flowers if desired.
