Twice-Baked Stuffed Yams with Harissa and Red Lentils

Directions

1. Roast yams whole in the oven by piercing them several times with a fork or paring knife and placing in a 350 F oven. Check after 20 minutes and then every 5 - 10 minutes thereafter. Remove from oven when flesh feels soft throughout when tested with a paring knife. Alternatively, yams can be cooked in the microwave. Pierce several times with a knife and fork and microwave on high in 2 - 3 minute increments.
2. Add red lentils to 2 cups of water and bring to a boil. Once boiling, drop heat to a simmer, cover, and continue simmering for 20 minutes. It's okay if the lentils loose their shape- you're going to be blending them anyway. If there's any liquid remaining, drain it off now.
3. Slit yams lengthwise and scoop flesh into a food processor. Reserve yams skins. Add drained cooked lentils, and Harissa through black pepper. Start on the lower end of the spectrum for the harissa (mine isn't terribly hot, but has a deep and smoky flavour profile, so I was able to add the full 3 Tbsp). Once blended, add onions and garlic and pulse briefly to combine.
4. Fill reserve yam skins with yam and lentil mixture. Place on baking sheet and return to oven for another 15 - 20 minutes until hot throughout and beginning to brown.
5. Allow to cool slightly and top with lemon tahini sauce.
