Notes

SUBSTITUTIONS:
  • Vary the veggies! Try regular potatoes, carrots, butternut squash, rutabaga, or turnips.
TIP:
  • Always look lentils over for stones, sticks and odd-looking bits. I do this on an inexpensive white paper plate to easily add them to what I’m cooking.
MAKE AHEAD:
  • Can be made up to 2 days ahead. Cool thoroughly.
  • Reheat on the stovetop or in the microwave for individual servings.
FREEZER-FRIENDLY:
  • Cool thoroughly and package as desired. Freeze up to 2 months.
  • Thaw in the refrigerator or microwave.  Reheat on the stovetop or in the microwave.
