To make the slaw, combine the mango, cabbage, cilantro and green onions together in a large bowl. In a small bowl, whisk together the lime juice, honey, chili garlic sauce and salt. Pour the dressing over the slaw and stir until well combined. Cover and refrigerate to let marinate until ready to serve.
To make the glaze, whisk together the honey, soy sauce, sesame oil, garlic chili sauce, garlic and ginger in a medium bowl. Set aside.
Pat the salmon dry with paper towels. Slice the salmon into 1 1/2 to 2-inch chunks. Season the fish with salt, garlic powder and smoked paprika.
In a large nonstick skillet set over medium heat, heat the sesame oil. Add the salmon in a single layer and cook for 3 to 4 minutes per side, turning gently.
Reduce the heat to medium low and add the glaze, gently turning the salmon pieces to coat them. Continue heating and tossing until the glaze has thickened and is clinging to the fish.
Divide the quinoa between 4 bowls. Top with a portion of the cooked salmon, then add your desired vegetables, mango slaw and spicy mayo, if using.
