Preheat your oven to 450 degrees f. and line a large sheet pan with parchment paper.
Add the squash and sprouts to your sheet pan; Drizzle with oil, Season with sea salt and pepper. Toss to coat everything well.
Arrange them in a single layer.
Roast for 15 minutes or until the veggies are just tender. Remove the pan from the oven and incorporate the pepper and onion. Place your pan back into your oven. Roast for 10 minutes.
Meanwhile, in a medium bowl, combine all of your honey mustard sauce ingredients and whisk together really well. Reserve/remove half of this sauce and place it in the fridge (untouched by raw shrimp) to serve later with your meal prep bowls.
Add your raw shrimp into the remaining honey mustard sauce in your bowl and toss to coat them really well.
Once your veggies are finished roasting, make some space on the sheet pan and add the honey mustard shrimp. Back into the oven one more time. Roast for 6-8 minutes, or until the shrimp are pink and opaque.
Serve immediately while hot, or allow to cool completely for meal prep.
