Instructions
Preheat the oven to 475 degrees Fahrenheit (I used the convection setting on my oven, although if you don’t have that option, it will still work.). Place a large rimmed baking sheet into the oven at the same time, so that it heats up while you are prepping all the ingredients.
Scrub the potatoes really well and cut them into 1 – 1½ inch pieces. Place them into a medium pot, and fill it with water, so that the water is just barely covering the potatoes. Bring it to a boil, reduce to a simmer and cook for about 5 minutes, covered, just until the potatoes are halfway cooked through. Drain the potatoes.

Meanwhile, cut the mushrooms in half or in quarters if they are very large. Slice the onions into thick half circles. Cut the bell pepper into 1-inch pieces, and slice the sausage into 1-inch pieces.
In a large bowl, combine the onion, bell pepper, mushrooms, olive oil, minced garlic cloves, fresh thyme salt, freshly ground black pepper and a mixture of dry herbs.
When the potatoes are halfway cooked, gently toss them with the mushroom and pepper mixture, along with the sausage.
