Preheat the oven to 400 F (200 C). Prepare a sheet pan with cooking spray, foil, or silicone baking mat and set aside.
In a large mixing bowl, combine the olive oil, honey, dijon mustard, paprika, cayenne (if using), and salt and pepper. Mix until fully combined and taste the mixture. Add more honey, cayenne, salt, etc. to suit your taste preference.
Add the potatoes, green beans and onions to the bowl with the sauce. Mix well until the veggies are evenly coated in sauce. Arrange the veggies in an even layer on the prepared baking sheet.
Add the sausage links. You can put the sausage right on top of the veggies--the fat/oil from the sausage will flavor the veggies. My sausage package came with 5 links, so I went ahead and baked all 5. See recipe notes about using fully cooked sausages.
Bake for 30-35 min until the potatoes are fork tender and the sausage is browned and fully cooked (internal temperature 160 F/71 C).
Let everything cool fully before dividing between three meal prep containers. That's it!
