Preheat the oven to 400°F (205°C).
Cook the rice according to the directions on the package.
Make the salmon: Place the salmon on a foil-lined baking dish and season with salt and pepper. In a bowl, mix the lemon juice, melted butter, and parsley. Lather the top of the salmon with half of the lemon butter.
Bake for about 10 minutes at 400°F (205°C), to an internal temperature of 130°F (55°C) using a thermometer. Baking time will vary based on your fish fillet thickness. While the salmon is baking, make the vinaigrette and salad.
Prep salad ingredients per instruction above. Place the spring mix in a bowl with cucumber and onion on top. Use a vegetable peeler to shave the carrot onto the top of the salad.
Whisk together ingredients for the vinaigrette and season with salt and pepper to taste. Dress the salad before serving.
Finish the rice: Once tender, fluff with a fork. Season with salt and pepper to taste. Cover with a lid to keep warm until you are ready to serve.
Finish the fish: Brush the remaining lemon butter over top. Set aside to rest for 5 minutes. While resting, make the peas.
Melt the butter in a non-stick pan over medium heat. Add peas, and season with salt and pepper. Cook, stirring frequently until peas are tender and heated through (about 3-5 minutes).
Toast the bread in a toaster oven.
Finish the salad: Dress with the vinaigrette.
Serve: Enjoy the salmon with rice, peas, side salad, bread and butter, and water.
