Swiss Chard and Caramelized Onion Tacos
from Mexican Everyday, by Rick Bayless
Serves 4

12 oz. bunch of Swiss chard, thick lower stems removed (10 oz. cleaned spinach can be used instead)
1 1/2 tbl. oil
1 large onion, thinly sliced
3 garlic cloves, finely chopped
1 tsp. red pepper flakes (add more or less depending on how spicy you like it)
1/2 cup vegetable broth (water works too)
Salt
12 warm corn tortillas
1 cup (4 ounces) Queso Fresco or other fresh cheese such as feta or goat cheese
Smoky Chipotle Salsa for serving

Slice the chard into 1/2-inch ribbons. Heat the oil in a large skillet over medium-high heat. Add the onion then cook until golden brown, about 4-5 minutes. To the onions add the red pepper flakes and garlic. Stir for about 20 seconds until you are hit with the aroma of the garlic then immediately add the broth or water, 1/2 teaspoon salt and the greens. Adjust the heat to medium-low then cover the skillet. Cook until the greens are almost tender. For Swiss chard this will be about 5 minutes. Spinach only takes about 2 minutes.

Uncover the pan, adjust the heat to medium-high then cook until the juices have reduced significantly and merely glaze the greens. Taste and add salt if you think it needs it.

Serve with the corn tortillas, crumbled fresh cheese and Chipotle salsa.
