Healthy, Vegan Mexican Food

These paleo cauliflower rice fajitas came about due to a craving for Mexican that just had to be dealt with. Lime, cilantro, avocado, salsa, I needed these flavours! With my current nutrition goals, I wanted something low in carbs with healthy fats and lots of veggies to fill me up.

To create the “taco meat” for the fajitas I used a mixture of cauliflower rice and walnuts and it worked out beautifully. It’s filling, flavourful and has an awesome texture perfect for fajitas, burritos and tacos. Paired up with Mexican spices, plenty of avocado and spicy cooked peppers, you’ll love this healthy, low carb, plant-based alternative to ground beef. You could also use the lentil taco “meat” from my lentil tacos or vegan tostadas in these. This chimmichurri sauce or tomatillo sauce would also be a delicious addition!

Try It In A Tortilla

You can always use tortillas as an alternative to the romaine lettuce taco shells. The romaine makes for a nice light meal but if you want something more substantial, go ahead and wrap up all the fillings in a tortilla. You could use small tortillas to make tacos or large tortillas to make burritos. They can even be made ahead as part of food prep, rolled up in tortillas and either frozen individually for a take on microwave-burritos, or packed in the fridge for a healthy pre-made meal you can enjoy during the week.

Turn it Into A Burrito Bowl

Another option to the romaine lettuce shell or tortillas, is to use the romaine to make a bed of lettuce, then add all the toppings to make a delicious cauliflower rice burrito bowl! Add the romaine to a bowl, top with cauliflower rice, peppers, avocado, black beans, cilantro, lime, salsa and dig in! You can even skip the romaine and just add the toppings to a big bowl of cauliflower rice. Cauliflower rice burrito bowls are a good option for weekly food prep too. You can read more about making burrito bowls for food prep in this post. So many delicious options!
