I honestly do not remember where the original recipe came from (I think Epicurious.com) but when squash is available I use it and enjoy every bite. When I first made this my husband had THAT look on his face (eew not liking what I see) but one bite and he was hooked! Trust me this is so sweet and delicious it will become one of your favs on a Saturday meal of soup and pizza (which is what we do on Sats...soup& pizza or soup and paninis). ENJOY this low cal delight!!
Toss squash with 1 tsp oil, salt and pepper. On a baking sheet, cook squash until soft and lightly browned (15 - 25 mins--depending on your oven, mine runs very hot )stirring halfway through. Set aside.
In a large skillet over med-high heat add remaining oil. Cook onion (add 1/4 tsp salt), stirring until LIGHT brown. Add 2 Tablespoons of water, cook stirring until GOLDEN ( 5 mins).Remove from heat
Turn oven up to 450(once squash is cooked of course). Sprinkle flour on flat surface and press dough into a 15 inch circle or 10" x 16" in rectangle(I use a rolling pin). Top with squash, onion, spinach, cheese and thyme.
Dust a pizza stone or inverted cookie sheet /w/ cornmeal; place pizza on it. Bake until crust is crispy and cheese melts. Depending on your oven this should take anywhere from 8 - 12 minutes.
THIS IS JUST A TIP--when I use dried herbs such as the thyme in this recipe...rub the thyme well with your finger tips. This releases the natural oils in the herb/spice and brings out the flavor!
