Vegetables bathed in vinegar are typical condiments in Mexico, but you can bring them to the center of the plate as a filling for a taco. If you want spice, add the chipotle, or garnish with some salsa. If salt is an issue, use ranchero rather than cotija cheese.

Cauliflower and Red Onion Tacos Recipe (2)

Preparation

  1. Step

    1

    Place the cauliflower and onion in a steaming basket over 1 inch of boiling water. Cover and steam 1 minute. Lift the lid for 15 seconds, then cover again and steam for 5 to 8 minutes, until the cauliflower is tender. Refresh with cold water and drain on paper towels.

  2. Step

    2

    In a large bowl, mix together the garlic, cilantro, capers, vinegar and olive oil. Season with salt and pepper. Add the cauliflower and onion and toss together. Marinate, stirring from time to time, for 30 minutes if possible before serving. For an added kick, stir in the chili or chilies. Transfer the mixture to a skillet and heat through over medium heat.

  3. Step

    3

    Warm the tortillas. Top with the marinated vegetables and a handful of romaine, sprinkle on the cheese and serve.

Tip

  • Advance preparation: You can make the cauliflower and onion mixture up to a day ahead, but omit the cilantro until shortly before serving so that its color doesn't fade. The filling keeps well in the refrigerator for up to 5 days.

Zoe

Very good. In order to get more flavor I roasted the cauliflower and onion until browned. I added lime marinated chicken and avocado slices on the side for those who wanted them, which were nice but not critical.

I live overseas and since I didn't have cotija, used a salty crumbly sheep's milk cheese (brebis) from France, and lime juice in place of vinegar. I also used gem lettuce leaves in place of tortillas. A big hit with my guests, and I'll definitely make it again.

I make this mixture at least every other week but instead of using it for tacos I use it as a side. Love the flavors . When I am mixing it up my whole kitchen has a delicious smell as I usually sit on the counter to marinate and cool.

Bitwell

I added some cumin and more garlic to this recipe, but instead of steaming I rubbed the marinade into the cauliflower and then roasted it - allowed the flavours to come together and it was great.

Maya H.

I’d love to know what the purpose is of steaming for 1 minute, then lifting the lid for 15 seconds before finishing the steaming.

Kathy

It needed much more in flavors, next time I will adjust.

mark

Agree with roast and more spice. I marinated the cauliflower mix for a couple hours and then roasted it. Added cumin. Was delicious.

Virgina

Well, I should've read the comments and roasted the cauliflower and onion for better flavor. The people that liked this recipe changed it up a lot. As written it's pretty blah, and not a good filling for tacos. The addition of lime juice and cumin would probably help a lot. Not sure if I'll bother with this again.

Really delicious! Taking a cue from others, I tossed the cauliflower and onions (and a bit of yellow sweet pepper) with cumin and evoo and roasted them at 400 for 20 minutes before tossing with chipotle etc. Couldn’t find cilantro and didn’t miss it. Used feta, a good salty counterpoint.

Scott

This is definitely more of a recipe for a side for tacos or a topping, definitely not the filling. I agree with the other commenters that roasting the cauliflower and onion gives a much better and more savory flavor akin to what goes in a taco.

Bitwell

Bob

I added carrots and roasted (approx 30min at 425 degrees) both the cauliflower and carrots with the red onion. Used white wine vinegar, and crushed the garlic through a garlic press. The raw garlic in the marinade adds a really nice complexity. This was a total hit with everyone who tried it.
