FOR THE SQUASH:
3 to 4 zucchini or any variety of summer squashes, cut into 1-inch pieces
Extra-virgin olive oil, for drizzling
Kosher salt and black pepper
FOR THE MOLE:
4 tablespoons grapeseed oil
1/4 small white onion, roughly chopped
1 small garlic clove, sliced
1 poblano chile, sliced
1 güero chile, banana pepper or New Mexico yellow chile, sliced
1 cup finely diced tomatillos
1 cup roasted shelled pistachios
1 cup fresh cilantro leaves
2 fresh or dried hoja santa leaves
1/2 cup baby spinach
1 cup assorted greens, such as cilantro leaves, amaranth leaves or purslane
2 cups cooked white rice
Heat the oven to 350 degrees. Place the squash on a baking sheet. Drizzle with olive oil, season with salt and pepper and toss to coat. Roast until lightly brown, about 15 to 25 minutes.
Meanwhile, make the mole: In a pot, heat the grapeseed oil over medium heat. Add the onion and garlic and cook, stirring occasionally, until translucent, about 5 minutes. Add the chiles and cook, stirring occasionally, until soft, about 5 minutes. Add the tomatillos and cook, stirring occasionally, until soft, 5 to 8 minutes.
Add ? cup water and the pistachios and simmer for 5 minutes. Remove from the heat and transfer to a blender along with the cilantro, hoja santa and spinach. Blend until smooth, about 3 minutes. Season with salt to taste.
Serve the mole warm, with the roasted zucchini. Top with greens and serve rice and tortillas alongside.
Leftover mole can be stored in the refrigerator in an airtight container for up to a week. To reheat, add a bit of water and warm in a pot over medium heat.
