For oven fries this is what I do:
In a large bowl I put vegan Worcestershire sauce or low sodium soy sauce (about 1/3 cup), and sprinkle Mrs dash, or Oregano, a little seasoning salt or garlic powder (depends on your mood).
Mix it all together in the bowl and add cut up potatoes.
Stir or toss to coat them.
Bake on parchment paper on cookie sheets or good non-stick sheets in the oven at 350 or so for 25-30 minutes, depending on how thick they are.
The sauce gives them a little crisp and a lot of flavor. My husband LOVES these.
If you have sodium issues you can also use Balsamic vinegar instead of low sodium soy sauce, it is just as yummy , and a little tangy.
