One package of shiratiki noodles* (40 cal for 2 servings), Laughing Cow light swiss wedges (35 cal), a dash of milk, a tablespoon of a hard salty cheese (parmesan, aged gouda, etc), and salt and pepper. The whole dish is under 100 calories. I often add turkey sausage and steamed broccoli. It's my go-to super-low-cal meal.
