Preheat your oven to 420
Place all your veggies (except for the tomatoes) on 1-2 baking sheets. I normally use 2 sheets so I don't overcrowd the pan.
Season your vegetables with whatever you like. Cook them for approx 25 minutes or until they are roasted to your preference. Remove the baking sheets. Allow the vegetables to cool to room temperature.
While the vegetables are cooking/cooling, slice your sausage and cube your cheese.
Once the vegetables are cool, divide them evenly into 10 lunch containers. Top the vegetables with the sausage, then the cheese, then finally the tomatoes.
Cover each container with a lid and store them in the fridge for 5-6 days.
When it's time to eat, you can warm the lunch in the microwave or dump the contents into a pan on the stove and reheat them that way.
Sever with your favorite hot sauce, mustard, or any other sauce you enjoy.
