Preheat oven to 400 degrees. Spritz a rimmed half sheet pan with non-stick spray.
Quarter the potatoes and add to a mixing bowl with 1 tablespoon of oil.
Add the seasonings to a small bowl and stir to combine.
Sprinkle about three-quarters of the seasoning over the potatoes and toss to coat.
Arrange the potatoes on the prepared baking sheet.
Bake for 10 minutes.
While potatoes are baking, toss the broccoli with the remaining oil and seasoning.
After 10 minutes, remove the potatoes from the oven and stir. Push potatoes to the side and add the broccoli to the pan. Arrange the vegetables along one half of the pan, leaving space for the mini meatloaves.
To make the meatloaf:
While the potatoes are roasting, combine all of the meatloaf ingredients in a bowl and stir with your hands to combine.
Shape into 4 mini meatloaf shapes.
Place the meatloaves in the open space on the baking sheet.
Return to the oven for 10 minutes.
To make the meatloaf sauce:
While the meatloaf is cooking, whisk together all of the sauce ingredients in a small bowl.
To finish:
After meatloaf has baked for 10 minutes, remove from the oven and top with the sauce.
Carefully stir the vegetables and return to the oven. Continue baking for 15 minutes or until the internal temperature of the meatloaf reaches 165 degrees.
Serve while hot.
Notes
You can swap out the broccoli for Brussels sprouts, green beans, or asparagus if preferred.If you'd like extra meatloaf, double the recipe and cook the mini meatloaves on a separate pan.
