Tips for Lentil-Walnut Taco Filling
I like to start with petite brown lentils. My favorite variety is Pardina, also known as Spanish lentils. They work especially well in this recipe because they hold their shape when cooked which makes them easier to drain.
I like using my electric pressure cooker to make Instant Pot Lentils. They are also good cooked in a slow cooker or on the stove. Easy!. No matter how you cook them.
For this recipe, it’s important to thoroughly drain the lentils in order to get rid of excess moisture. The easiest way to do that is to drain them immediately after cooking.
To further reduce the moisture content, spread the cooked lentils out on two dinner plates or a baking sheet until cool.
It also helps to cook the lentils ahead and refrigerate them so they are firmer.
Freeze extra cooked lentils in a zip-top bag to make them easier to measure out and defrost for the next time you want lentils in a hurry. Or double or triple the lentil-walnut taco filling and freeze for later. That’s cooking smarter, not harder. That’s what I call Cooking Forward.™ It’s such a time-saving strategy for creating quick and easy healthy meals.
My Secret Ingredient
I like to add two tablespoons of mushroom powder to add extra flavor, umami, and to help absorb excess moisture.
I get shiitake mushroom powder from a local mushroom grower, Duckabush Mushrooms, that sells at the local farmers market.

If you don’t have mushroom powder, you can grind dried mushrooms into a fine powder with a blender or food processor.
