Lay out five pieces of tinfoil, large enough to fold into packets over sausage and veggies. Spray each piece of foil lightly with cooking spray to help avoid sticking. (Omit this step if you have heavy duty non-stick foil -- I just used regular foil here, though.)
Slice up your sausage and chop the vegetables, then place them all in a large bowl. Add seasonings, minced garlic, and olive oil and toss to coat.
Distribute meat and veggies evenly across your prepared pieces of foil.
Fold them up into packets, making sure that they are completely and tightly sealed so that steam can't escape.
To cook your sausage, pepper, and potato foil packets:
In the oven: Place foil packets on a rimmed baking sheet and roast at 425 degrees for 30-35 minutes, or until potatoes and veggies are tender and sausage is cooked through to temperature.
On the grill: Place foil packets on a preheated grill over medium high heat, close grill, and cook for 25 minutes, or until potatoes and veggies are tender and sausage is cooked through to temperature.
Open packets carefully, as these will be very hot and steam will escape.
You can mix up the veggies and seasonings here as desired; just be sure to season the packets generously. I was actually originally going to use green beans rather than bell pepper, but my store was out this week, so I used the one sad pepper left in my fridge instead. Try zucchini, red onion, corn on the cob (sliced into sections)...
