Lentils & rice is a classic Arab combination that goes back to medieval times. I’ve seen it prepared many ways—from a rice dish with just a bit of lentils to mostly lentils with a touch of rice. As for me, I like to make it half/half, a cup of each. I also add a chopped up carrot. Though non-traditional, the carrot adds color and interest to an otherwise plain-looking dish. Finally, do not skimp on the onion. More than a garnish, the onions flavor the dish in such a way that you’ll find yourself and a fellow diner fighting over the last remaining bits of onion. If you love onions, I suggest frying up three onions or even four. Trust me on this.
