Everything in the Fridge Lentil Soup

We make this a lot. Tonight we had friends over so it tasted even better than usual. The recipe varies, according to what's laying around in the 'fridge, but the split red lentils (masoordal) and coconut milk are constants. Sometimes a sweet potato makes it in. Sometimes whole cherry tomatoes. Red lentils cook quickly and are extra-good. The trick is to "toast" the lentils in a wee bit of olive oil alone in the pan for a few minutes before adding any liquid. Then add everything and simmer away...
Squeeze lime juice on top just before serving.
