Step 1

In a medium saucepan, combine the lentils and enough water to cover by at least 1 inch (2.5 cm). Bring to a boil over high heat; reduce heat to low and simmer, uncovered, for 10 minutes (the lentils will be slightly undercooked). Drain and rinse under cool water.

Step 2

Place lentils in a food processor. Pulse until finely chopped with only a few irregular pieces. Scrape the lentils into a large bowl (no need to clean the food processor).

Step 3

Place the mushrooms and onions in food processor bowl. Firmly press beets between layers of paper towel to remove excess liquid; add to food processor. Process until very finely chopped, but not a puree. Add to lentils in bowl.

Step 4

Add remaining ingredient to bowl. Stir everything together until blended. Taste; adjust the seasonings to suit your tastes. Use immediately or see storage options for future use!
