Lentils are a staple of so many diets and cuisines. For starters, they’re gluten-free, virtually fat-free, and low in calories. Red lentils are high in fiber, protein, and packed with Vitamin B and potassium. As if we needed anything else good to say about them, they’re also a good source of iron.

There’s no need to pre-soak lentils, and you don’t need to cook them for hours like other beans. Red lentils are the champion of the last-minute cook’s pantry. Did we mention what a great base they make for soups? Equally, they’re ideal for a slow cooker recipes that simmer for hours.

Condiments Galore

This steaming bowl of Turkish Red Lentil Soup demands a table filled with all the appropriate toppings. Our suggested fresh mint and parsley, chopped or torn, is non-negotiable; it adds so much fresh flavor. If you can’t source any fresh herbs, dried mint is still better than nothing. A squeeze of lemon goes a long way too. I like adding fresh chili too, or a healthy dollop of plain yogurt!

Mooching through the cupboards and wondering what to eat? As long as the lentils are there and a few odds and ends, you can always rustle something up. We have many more lentil recipes on Skinny Ms. Right now, I’m loving this Rosemary and Lentil Soup as well as this Easy Lentil Vegetable Loaf.
