Step 1

Place the onion in a large, shallow saucepan, and sauté over medium heat until translucent (about 3 to 4 minutes), adding water 1 to 2 tablespoons at a time to keep the vegetables from sticking. Add the garlic and continue to sauté for about 1 minute. Add the jalapeño and sauté for about 2 minutes. Add the ginger, curry powder, garam masala, and turmeric (if using). Stir to fully combine and cook for about 2 minutes more, adding water as necessary.

Step 2

Add the broth, sweet potatoes, and lentils. Stir to combine. Cover and bring to a boil, then reduce the heat and cover again, this time leaving the lid open a crack. Simmer for about 20 minutes.

Step 3

When the lentils are tender and the liquid has decreased, add the yogurt, lime juice, and chard, and cook until the chard is just starting to wilt. Add the salt and the pepper to taste, stir to combine, and remove from the heat. Serve warm.
