Ingredients You’ll Need
Most of these items are likely already waiting in your pantry. Using seasonal produce at its best makes every bite taste better.
- 2 cups sweet potatoes, peeled and cubed
- 1 cup dried brown or green lentils, rinsed
- 4 cups curly kale, stems removed and finely chopped
- 1/2 cup tahini
- 2 tablespoons fresh lemon juice
- 1 tablespoon maple syrup
- 1 clove garlic, minced
- 2 tablespoons olive oil, divided
- 1/4 cup pumpkin seeds
- 1/4 cup dried cranberries
- 1/2 teaspoon kosher salt
- 1/4 teaspoon black pepper
Step-by-Step
- Preheat oven to 400°F (200°C). Toss sweet potato cubes with 1 tablespoon olive oil, salt, and pepper. Roast on a baking sheet for 20-25 minutes until tender. Set aside to cool.
- Place lentils in a small pot with 3 cups of water. Bring to a boil, then reduce heat and simmer for 15-20 minutes until tender but not mushy. Drain and let cool completely.
- In a medium bowl, combine chopped kale with 1 tablespoon olive oil and a pinch of salt. Massage the leaves with your hands for 2-3 minutes until they become dark green and tender.
- In a small bowl, whisk together tahini, lemon juice, maple syrup, and minced garlic. Add water 1 tablespoon at a time until a pourable dressing consistency is achieved.
- Gather four 32-ounce mason jars. Divide the tahini dressing equally among the bottoms of the four jars.
- Layer the ingredients into each jar in the following order: cooled lentils, roasted sweet potatoes, massaged kale, pumpkin seeds, and dried cranberries.
- Seal the jars tightly and refrigerate. When ready to eat, shake the jar vigorously to distribute the dressing or pour into a bowl and toss.
Best Ways to Enjoy It
When hunger strikes, just shake the jar and enjoy. You can eat it straight from the glass for minimal cleanup at work. Or, pour it into a wide bowl for a restaurant-style experience.
Pair this salad with a warm cup of herbal tea. It makes for a satisfying and peaceful lunch break. Pack it into your bag and feel confident about your healthy choices.
How to Store Leftovers
Store these jars in the refrigerator for up to four days. The tahini dressing stays safely tucked at the bottom. This prevents the kale from becoming limp or soggy. It actually tastes even better on day two as the flavors meld.
Avoid freezing these jars as the texture of the kale will change. If you are prepping for a long week, make the components ahead. You can assemble the jars quickly on Sunday evening.
Tips for Best Results
- Don’t skip massaging the kale with olive oil and salt.
- Ensure the lentils and potatoes are completely cool before layering.
- Use green or brown lentils as they hold their shape well.
- Place the dressing at the very bottom to keep everything fresh.
- For a fall twist, add a dash of cinnamon to the potatoes.
- Double the batch if you are feeding a hungry family.

Ways to Switch It Up

- Add a sprinkle of feta cheese if you do not follow a vegan diet.
- Use quinoa instead of lentils for a different protein source.
- Replace pumpkin seeds with toasted walnuts for a buttery crunch.
