If using sirloin steaks, follow same instruction as chicken in Steps 1. In Step 2, place a medium non-stick pan over medium-high heat and add 2 tsp. olive oil. Add steaks to hot pan and sear until lightly browned, 2-3 minutes. Transfer steaks to baking sheet, seared side up, and add panko mixture, pressing lightly to adhere. Roast in hot oven until steaks reach minimum internal temperature, 10-12 minutes. Remove steaks to a plate and tent with foil. Roast vegetables until tender, 7-8 minutes.
If using salmon, follow same instruction as chicken in Steps 1 and Step 2. Roast in hot oven until salmon reach minimum internal temperature, 13-15 minutes. Remove salmon to a plate and tent with foil. Roast vegetables until tender, 4-5 minutes.
