Preheat the oven to 400°F. Place the salmon on a sheet pan and season with salt and pepper.
Bake in the preheated oven for 15–18 minutes, or until cooked through.
Meanwhile, cut the mango and avocado into ½ inch pieces. Seed and finely dice the jalapeño. Slice the green onions thinly (you will use both the white, light green, and dark parts here).
Place mango, avocado, jalapeño, and green onions in a bowl with the chopped cilantro, lime juice, olive oil, and a pinch of salt. Stir gently to combine. Taste and season with additional salt and pepper as desired.
Place the salmon on a serving platter or on dinner plates, and top with the salsa. Serve immediately.
Notes
Tip #1: You want mostly ripe avocados for this recipe, which means they give only slightly when pressed. If an avocado is too ripe, it’ll turn to mush as soon as you stir the salsa.Tip #2: This will create plenty of mango avocado salsa. I love to scoop up the extras with tortilla chips, plantain chips, or pretzels.
