These Slow-Cooker Vegan Bean Tacos with Avocado and Walnut topping cook while you’re at work! They are a healthy, filling and low calorie slow-cooker taco recipe without any meat! 

I’m really excited about this post because it’s my first ever video recipe, and it’s showcasing one of my favorite video creations to date.  As a member of theThe Recipe ReDux, I was challenged to create a recipe featuring California Walnuts. I absolutely love walnuts because they are a delicious and versatile ingredient that pair perfectly with other nutritious foods to create a tasty and healthy meal. One ounce of walnuts has 2.5 grams of the omega-3s (the healthy fat) , 4 grams of protein and 2 grams of fiber to keep you feeling full.

With these delicious and nutritious nuts, I decided to recreate one of my favorite dishes from a local restaurant.  The Thirsty Koala in Astoria, NY  features delicious Australian cuisine, including a vegan taco with beans, walnuts and avocado.  I decided to use my skilled palate to attempt to make a copycat version of my favorite restaurant meal, and I must admit that I did pretty well! This version is made in a crockpot, so you can set it and forget it, and you never even have to turn on your oven!

    This looks soooooo good! I love the San Marzano tomatoes you threw in the mix! Such a flavor packed recipe and nutrient dense, too!

    Really great video…love the music,color and feel of the whole piece. Looks so simple to make with most ingredients on hand.

    Be careful with the dry beans – kidney beans need safety boiling before cooking if included and in my 30 years of vegetarian slow cooker eating I wouldn’t expect dry pulses to really cook properly on the low setting in just 6 hrs. Maybe it’s time I bought a more modern slow cooker, they could be faster?!

    • Natalie Rizzo, MS, RD

      This was a mixed bag of beans, and it cooked surprisingly fast! I have a newer crockpot though, so maybe that’s it!

    What size is your crockpot? I’d like to try doubling this recipe. Thanks!

    • Natalie Rizzo, MS, RD

      I have mini 2 quart one. If you double it in a regular size crockpot, it should work!
