First, wash all of the vegetables. Next, dice the zucchini, squash, and potatoes. Make sure the potatoes are cut into pretty small pieces, you want everything to cook evenly so it helps to make everything about the same size.
Then cut the broccoli and slice the onion and place all of the vegetables onto a baking sheet lined with foil and sprayed with oil.
Drizzle or spray olive oil over the vegetables, then sprinkle some salt, pepper, and herbs de provence over all of the veggies. Bake at 400 for 30 minutes, stirring/flipping the vegetables every 10 minutes.
I love these Oven Baked Vegetables as a side dish and as a main course for lunch. I also like to add a little dollop of sour cream on top!
