Hearty Plant-Based Tacos with Lentils, Black Beans & Mushrooms

Celebrate National Taco Day with these hearty plant-based tacos made with lentils, black beans, and mushrooms. High in protein, full of flavor, and perfect for hard or soft shells — a wholesome twist on classic tacos!

There are few foods as universally loved as tacos. Whether you like them crunchy or soft, spicy or mild, loaded with cheese or piled high with veggies—there’s a taco for everyone.

And  National Taco Day is the perfect excuse to celebrate with a wholesome, plant-based version that’s packed with protein, fiber, and flavor.

💚 Why Go Plant-Based?

Plant-based tacos aren’t just for vegetarians—they’re for anyone who is interested in including more plant based meals in their rotation.
They’re rich in nutrients, easy on digestion, and can be customized endlessly. Plus, when done right, you won’t even miss the meat!

One of the best ingredients to use in a meatless taco is lentils. These tiny but mighty legumes are nutritional powerhouses—high in protein, iron, and fiber—making them an ideal swap for ground beef. Lentils add a hearty, satisfying texture that soaks up spices beautifully. They also help keep you full longer, support steady blood sugar levels, and are incredibly budget-friendly. It’s no wonder they’re a staple in so many plant-based kitchens!

In fact I use them wherever I can including homemade pizza (yes even on my grand daughters!)
