  • The nutrition facts do not take into consideration the addition of salt and pepper to taste.
  • If you are not a fan of sweet potatoes, you can use white potatoes or any potato of your choice.
  • No lentils? No problem! You can swap them out for any cooked canned beans, just be sure to add them in at the end with the greens so that they keep their shape/don’t overcook.
  • You can use spinach in place of the kale, or a green of your choice! Some greens are tougher than others and may require additional cooking, so just use your own judgement and preferences to adjust the cook time accordingly.
  • If you want to use dry herbs in place of the fresh, use 1/3 teaspoon dried thyme, 1/3 teaspoon dried rosemary and 1/3 teaspoon dried sage.
