  • 1/2 pound fresh spinach, finely minced
  • 1 teaspoon dry mustard
  • fresh black pepper to taste
  • 1/2 cup fine bread crumbs or wheat germ

Tips & Substitutions

For a firmer burger, consider adding 1/4 cup of oats or quinoa to the mixture. If you're out of cider vinegar, lemon juice makes a great substitute. To save time, prepare the lentils in advance and store them in the fridge. Remember to taste and adjust the seasoning; fresh black pepper really enhances the flavors. For a unique twist, try adding some chopped sun-dried tomatoes.

What can I use instead of walnuts?
