In a large bowl, combine the shrimp with the old bay seasoning.
Heat a large skillet over medium heat and drizzle in 1 tablespoon of your oil.
Add shrimp and cook until pink and opaque, about 3-4 minutes. Set aside on a plate.
In your same heated skillet add the remaining oil. Add in the sausage and cook just until it starts to get golden brown. Stir in all of your prepped veggies and garlic then continue to cook, stirring occasionally, until tender-crisp.
Season with sea salt and pepper to your taste. Return the shrimp into the skillet together with the parsley and toss with the veggies and sausage.
Serve immediately or allow to cool for meal prep.
Stays good in the fridge for up to 3-4 days.
