Boil a very large pot of water. Add a lid to the pot to speed the time it takes to boil.
Preheat oven to 425F/220C.
Lay out chicken onto a parchment lined sheet tray and season with salt and pepper.
Lay the salmon onto a parchment lined sheet tray skin side down, and season with salt and pepper
Bake both the chicken and salmon at 425F/220C
At around the 15 minute mark, check the Salmon. It's done cooking when the internal temp reaches 130-140F/55-60C.
The chicken should be done after cooking for between 20-25 minutes depending on the size of the breasts. They're done when the internal temperature reaches 150-160F/65-70C
Eat immediately or transfer salmon and chicken to wide, flat storage containers in the fridge (lid off) to cool.
Salt the now-boiling water well and add in chopped broccoli. Cook for about 90 seconds or until the broccoli has softened, but still has a little bite to it. Transfer the broccoli to a wire rack to drain. Then into paper towel lined containers for storage in the fridge.
Add the carrots into the boiling water and cook for 3-4 minutes until just tender, but still a little snappy. Transfer to a wire rack to drain.
Add the kale to the boiling water and cook for about 2 minutes. Transfer to wire rack to drain then load into paper towel lined storage containers.
Add the brussel sprouts to the boiling water and cook for 3-4 minutes. Transfer to wire rack to drain then load into paper towel lined storage containers.
Increase oven temperature to 475F/245C.
To cook the rice, combine 800g water with 600g rice and a very large pinch of salt. Stir and set to cook on the white rice setting. Store in a container or two in the fridge until ready to use.
Slice potatoes in half. Replace the parchment paper from one of the protein sheet trays with a fresh sheet and add on sliced potatoes. Add a generous squeeze of olive oil and a large pinch of salt. Toss on the sheet tray to coat and arrange potatoes cut side down.
Peel and cut sweet potatoes into bite size cubes. Replace parchment paper from the second protein sheet tray with a fresh sheet and add diced sweet potatoes. Drizzle with olive oil and salt and toss to evenly coat.
Add both trays of potatoes into the oven to cook at 475F/245C. Cook for about 25 minutes until roasted, tender, and charred around the edges. Transfer potatoes into paper towel lined containers and store in the fridge.
