initially i didn't want to cook it, i was afraid these two have too much moisture and i'll end up with a soggy pie. it's all good as long as you keep them in a strainer for 15-20 minutes. as an alternative to roasting the beets, you can steam them. get small ones if possible, they cook faster and they're easier to peel. be careful with them, that juice staines right to the bone. once they're cooked and cooled, slice them thinly and put them in a mesh with the artichokes.
stretch the dough to the size and shape of your baking vehicle. spread with tomato-based pizza sauce. sprinkle a good handful of grated parmesan over it. then alternate slices of beet, artichoke and mushroom. don't overcrowd it. then take 4 or 5 springs of thyme and run your fingers against the stem to get the tiny leaves off, and sprinkle them evenly. i also used some chopped sage, but that's not as vital as the thyme. give it a grind of pepper and bake at 425F for 15-20 minutes.
it's the best of both worlds. your kid gets pizzzzaaaaa! and you get a few veggies in her, and a grown-up lunch. the spinach is dressed simply with olive oil, champagne vinegar, dijon and honey. it makes a great companion for the pizza but doesn't steal its thunder. i think it would be lovely with a few dots of goat cheese, and/or a few asparagus tips. i plan to turn all these ingredients into a panzanella, stat. the aliens are still eating my brain.
