Coconut Red Lentils With Spinach, Cashews & Lime (Vegan)

In a large pot saute the onion in the olive oil over medium heat for about 5 minutes. While the onion cooks get the rest of the ingredients ready to go.
Add in the curry powder, mustard seeds, turmeric and red lentils - cook for another 5 minutes. Watch the lentils don't stick by stirring frequently and/or adding more oil if necessary.
Mix in the coconut milk, salt, lime juice and water. Bring to a boil then reduce heat to medium low, cover the pot and let simmer for about 20-25 minutes. Stir occasionally to prevent sticking. Unlikely, but if you find the lentils have absorbed all of the liquid and are still not cooked, add a bit more water.
Once the lentils are cooked they will break down quite a bit and you'll have a reasonably thick dahl like consistency. Stir in the cashews and spinach, along with cilantro if using. Give those ingredients about 3 or 4 minutes to warm through and then you're ready to serve. Garnish with additional cilantro, lime wedges and/or cashews.
