1poundItalian sausagesliced 1/2-inch thick (do not remove casings) mild, hot, or sweet is fine
1 1/2poundsred potatoesscrubbed and cut into bite-sized pieces
2medium to large zucchinihalved and sliced 1/2-inch thick
1large yellow or white onionchopped 1/2-inch squares
1orange bell pepperchopped 1-inch squares
1yellow bell pepperchopped 1-inch squares
1red bell pepperchopped 1-inch squares
Arrange oven racks so that both racks are somewhere near the center of the oven (you don't want the bottom rack right above the heating element).
Preheat your oven to 425°F. Lightly grease two baking sheets with cooking spray.
In a small bowl, stir together rosemary, garlic powder, salt, and pepper.
In a large bowl, combine sausage, potatoes, and zucchini. In a second large bowl combine chopped onion and bell peppers.*
Drizzle the contents of both bowls with half of the the olive oil and half of the spice mixture each, and then use clean hands to mix each bowl so that everything is well coated.
Pour half of the contents of each bowl onto both trays, and then mix well so you have an even mixture of sausage and veggies on each tray. Spread everything out so it covers the entire tray in a (mostly) single layer.
Bake both trays at once for 40 to 50 minutes, swapping the trays once halfway through. Dinner is ready when veggies are fork-tender and sausage is cooked through.
Serve and enjoy!
*If you have a bowl large enough to fit all the ingredients, you can combine everything in one.
