Get the items you will be needing together:
-Large square glass
-2 large potatoes
-Your preferred seasonings
Step 1-Pre-heat your oven to 350 degrees.
Step 2-Peal your potatoes and cube them, Then you can wash your squash and zucchini. Cut these into cubes as well. Do not peal them.
Step 3-Cover the bottom of the glass pan with olive oil, place all of your vegetables in the pan. Season. Be sure the olive oil covers the bottom of the pan.
Step 4-Place in oven and cook until all vegetables are soft. Usually about 30 minutes to an hour. Stir the vegetables occasionally to be sure they are not sticking. If they are, add a little more olive oil.
Serve with your main dish of choice, and enjoy. I enjoy it with baked chicken, it seems to bring out the flavor.
