This stuffed cabbage soup is a complete meal in a bowl, with plenty of fiber, protein, and veggies in each bite. Instead of using rice, this recipe uses dried lentils, but don't let that scare you away. They plump up in 30 minutes, just like rice, but increase the overall fiber and protein. As a result, this recipe has 35 grams of protein and 14 grams of fiber per serving, all for under 400 calories.
Heat a 5-quart or larger pot over medium-high heat and add a drizzle of olive oil. Once the surface is hot (about 2 minutes), add the onion and cook until it starts to soften, about 5 minutes. Then add the ground beef, 1 teaspoon of salt, and a ¼ teaspoon of ground black pepper. Use a sturdy spatula to break up the meat into small pieces until it's fully browned, about 8 more minutes.
Once the meat is cooked, add the minced garlic, oregano, paprika, and red pepper flakes. Stir until they smell fragrant, about 1 more minute.
Add the canned tomatoes and juices, plus the dried lentils, and shredded cabbage. Pour 6 cups of water into the pot and bring it to a boil over high heat. (Note: You'll need to add more salt later, but don't do it now. It can affect how quickly the lentils cook.) Once the soup is vigorously boiling, cover the pot with a lid and lower the heat. Simmer until the lentils are tender, about 25 minutes.
When the timer goes off, remove the lid and check the lentils for tenderness. I use a fork to lift out a few and taste-test, to make sure they don't have a bite to them anymore. Once the lentils are tender, season with another 1 teaspoon of salt and add the maple syrup. Stir well and taste-test again. I usually add another ½ teaspoon of salt after that, but your taste buds can determine the final flavor. As soon as you're happy with it, it's ready to serve.
