1. Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius).
2. Place salmon on a baking sheet lined with Gefen Parchment Paper. Drizzle with olive oil and sprinkle with salt and pepper. Bake for 25 minutes. Remove from oven and allow to cool. Transfer salmon to a bowl and flake it with a fork.
3. While the salmon is cooking, prepare the cauliflower rice: In a large frying pan, heat the oil. Add the cauliflower and sauté until lightly brown. Add one teaspoon salt and stir. Remove from heat and transfer to a bowl.
4. Add flaked salmon, soy sauce, sriracha, and mayonnaise. Mix together with a fork, mashing the salmon as you mix. Serve with slices of avocado and pieces of roasted seaweed. Garnish with French-fried onions, if desired.
