OVEN: Position a rack in the center of the oven and preheat the oven to 425ºF. Spray a nonstick sheet pan with cooking spray; set aside for now.
SALMON: Add the salmon piece to a bowl. Drizzle with avocado oil, soy sauce, and sriracha. Spread the salmon pieces out on the prepared baking sheet.
BAKE: When the oven has preheated, bake for 8-10 minutes depending on the thickness of the salmon. You might need to adjust the cooking time based on the thickness of the salmon.
SAUCE: While the salmon cooks, melt the butter in a hot pan on the stove over medium heat. Add garlic and sauté for 15 seconds when the butter melts. Add the honey and lime juice and stir to combine. Bring to a gentle simmer, then remove from heat. If the sauce separates, don't worry, just stir.
BROIL: When the salmon is done, spoon half of the prepared honey lime sauce on the salmon and broil or 30-90 seconds or until the salmon starts to develop a little color. Remove from the oven when the salmon browns.
BOWLS: Portion rice into bowls, top with the salmon pieces. Add avocado, cucumbers, and leftovers honey lime sauce as desired. Top with cilantro. Serve with lime wedges, sprinkle with sesame seeds, and add a squeeze of sriracha mayo if desired!
