1) If you don’t have time to make your dough, just pick up one of those store-bought varieties that’s already rolled out. It will likely be a bit smaller than this homemade version, but you can adjust your process accordingly.
2) Be sure to sauté mushrooms in batches so they cook in one layer, able to achieve a nice sear (and sear, as we know, equals flavor, which equals delicious). Julia Child was right when she said “Don’t crowd the mushrooms!” We want them to roast, not steam :)
