This is a very simple recipe from one of my mom's Syrian cookbooks. If anyone is interested, I can reccommend some great Middle-Eastern cookbooks.
2 cups lentils
6 cups water
salt and pepper to taste
2 large potatoes, olive oil and lemon slices
it calls for onions, and you could mince, sautee and puree or just use powder
Cook lentils for 15 min., add salt and pepper. add onions to cooked lentils, cut potatoes in cubes and add to mixture.
cook 10 min more
Use lemon as garnish
If you make a big pot of this and find it dry when you try to reheat it later, just add some water and lemon juice, and a little bit of olive oil. I am not super-senstive to fats, so I usually drizzle some good, flavorful olive oil (Spanish, for example), and a good squeeze of lemon. This is nothing fancy at all but it tastes good and is easy on the tummy. Lentils do have a good amount of insoluable fiber, so this is good for you but go easy!
