Pizza with potato, onion, and oregano

Again, this is a melding of several tasty-looking recipes, and is recorded here as a reminder: I have not yet made this. Taking Isa's excellent pizza dough from Vegan With a Vengeance, topped with what Saveur calls 'melted onions' - losing the fontina, and adding in its place a drizzle of miso-based white sauce in an attempt to provide the complex and savory bite of fontina, hopefully this combination will delight and warm!

THE DOUGH
copied from this blog, but amended)

1 cup warm water
1 1/2 tablespoons sugar
1 (1/4 oz) packet of active dry yeast
2 tablespoons olive oil (and more for drizzling)
3 cups flour
1 teaspoon salt
cornmeal for dusting

My directions for making this in a bread machine:

Add ingredients in order listed: yeast, sugar, oil, water, flour, salt. Set machine to the dough setting. When it's done, add a bit of oil on top so it doesn't dry out, but leave it in the machine to rise.

Let rise for 1 hour, then punch down and knead for another minute, dusting with flour if necessary. Form into a ball again, place back in the bowl, and let it rest for an hour or two.

Form into 1 or 2 crusts by stretching and/rolling.

TOPPINGS:
- Miso-based sauce
- Melted onions
- Potato (1 yukon gold, sliced 1/16" thick - but wait to do this 'til just before assembling the pizza, or else do ahead and immerse in ice water so it doesn't get brown)
- Fresh oregano

THE SAUCE
I think Esme's special sauce would work here. It tastes not a bit like good pecorino or the fontina called for the in the original pizza recipe, but in any case, is rich and creamy with a similar earthy savor, and would add a whole set of notes to this simple pizza.

Esme’s Special Sauce, which I amended here for a lighter touch with the miso and soy sauce (her recipe calls for everything in equal amounts) is so simple:

In a small bowl mix up the following:
2 T tahini
1 T white miso
1 T soy sauce, tamari or Braggs
2 T olive oil
2 T nutritional yeast
2 T lemon Juice or vinegar
A few cloves of garlic, finely minced or pressed.

MELTED ONIONS

4 thinly sliced or minced onions
1/4 c extra virgin olive oil
1 t sea salt*

*Amended from original amount of 1 T - commenters agree that's too much, and I do not like too-salty anything! In any case, the miso & soy sauce have their own salt. I may just leave this salt out altogether.

Directions: Stew on low heat for several hours. The goal is to have the onions break down into an onion jam. Saveur suggests topping your small saucepan with a circle of parchment paper, cut to fit, which will keep the onions moist.


TO ASSEMBLE PIZZA
Preheat oven to 475-500F

1. Lightly spread sauce on pizza base to within 3/4" of edge.
2. Now put on a layer of the onion jam, not too thick!
3. Top with a layer of thinly sliced yukon gold potato (1/16"); brush olive oil over the top of this.
4. Sprinkle fresh oregano and cracked black pepper.
5. If you want, drizzle just a bit more of the sauce over the top (this may make the pizza too wet or heavy, so be very judicious here).
6. Bake 8-10 minutes or until pizza is golden brown.
