Tacos with Mushrooms, Kale, and Chile-Caramelized Onions

Remember that new taco obsession I predicted? It has most definitely come to pass, yet another recipe theme from Joe Yonan I can't resist exploring. There's a long list of foods that become a tasty meal when wrapped up in tortilla with some cheese and hot sauce, but all the subtle additions that make these tacos much more than mushrooms, greens, and cheese.

They may share some spices and salty cheese with their predecessors, but these tacos are a different and delicious beast. The onions are infused with a familiar spicy smokiness, but the sprinkling of sugar amps up the caramelization and fuses all the flavors quickly. Mushrooms, while not terribly interesting on their own, are the perfect flavor sponges for vibrant spices used here, while also picking up a brown crust of their own along the way. The greens add a nice bit of nutrition, color, and freshness, completed nicely by the salty cheese and final dash of heat over the top.

Out of corn tortillas or not in the mood for tacos? This hearty, spicy, and earthy concoction could also be served over rice or other grains, happily wrapped up in a burrito, or topped with some runny eggs. No matter what you decide to do with this vegetarian taco filling, it won't leave your taste buds or belly disappointed.

Tacos with Mushrooms, Kale, and Chile-Caramelized Onions
adapted from Serve Yourself by Joe Yonan
serves 1

1 tablespoon extra-virgin olive oil

1/2 teaspoon ground ancho, chipotle, or other chile

1/4 teaspoon ground cumin

1/4 teaspoon ground cinnamon

1 small red onion, thinly sliced (about 1 1/2 cups)

3 cloves garlic, thinly sliced

1/2 teaspoon kosher or coarse sea salt

1/2 teaspoon sugar

3 or 4 corn tortillas, preferably homemade

6 ounces oyster, cremini, hen of the woods, or other meaty mushrooms, cut into large pieces
1/2 cup frozen or 1 to 2 cups fresh baby kale or spinach

1 ounce queso fresco, soft goat cheese, or feta cheese, crumbled

Salsa or hot sauce of choice, for serving

1. Heat the oil in a large skillet over medium heat. When it shimmers, sprinkle in the ground ancho, cumin and cinnamon and cook until the spices sizzle and are very fragrant, about 30 seconds. Toss in the onion slices, stirring to break them apart. Cook until the onion starts to soften, 3 to 4 minutes. Stir in the garlic, salt, and sugar. Decrease the heat to low and continue to cook, stirring occasionally, until the onions are very soft, about 10 minutes.

2. While the onions are cooking, warm the tortillas and wrap them in aluminum foil to keep warm.

3. Increase the heat under the skillet to medium-high, add the mushrooms, toss to combine, and cook, stirring occasionally, until the mushrooms exude their juices and are just shy of tender, 3 to 4 minutes. Add greens and cook, stirring frequently, until greens are warmed through and mushrooms are tender, another couple minutes. Remove from the heat.

4. Lay the tortillas out on a plate. Divide the mushroom-onion mixture among the tortillas. Top each with a few crumbles of the goat cheese, a bit of greens, and a drizzle of salsa, and eat.
