Preheat oven to 400 degrees.
Layer red potatoes, zucchini, yellow squash, onions, bell peppers, cherry tomatoes, and mushrooms on two medium baking sheets.
Mix olive oil, minced garlic, Italian seasoning, dried thyme, crushed red pepper, salt and black pepper to small bowl. Mix to combine, then drop spoonfuls of seasoned oil over prepped veggies on both baking sheets, use hands to toss and coat.
Roast in the oven for 18-20 minutes or until all vegetables are cooked through, be sure to check the potatoes. Remove both pans and stir after 10 minutes of roasting.
Serve as a side or toss in a power/grain bowl.
