Thank you to Iowa Beef Industry Council for sponsoring this post. And Thank you for supporting the brands that support me and allow me to continue to grow my blog. All opinions, recipe and photographs are my own.
Over the years I have probably tried all the tricks to get my kids to eat their dinner.
- Bribery? Check.
- Dousing it in Ranch? Check.
- Threatening them? Check.
- Pretending silverware are airplanes? Uh.. Check.
- Resorting to Sibling Peer Pressure? Double Check.
But even with all of that, I have found three things that have worked the best, time and time again.
- Make it Pretty.
- Make it Fun.
- Let them Help.
This Flank Steak tacos recipe totally fits the “pretty” and “fun” part!
I told my girls they were “Rainbow Tacos” and they devoured them.
I also always let my girls assemble their own tacos, which usually works like magic to get them interested in eating anything that goes on their plate.

Flank Steak is one of my favorite cuts of beef to use. It’s lean, its flavorful, its super easy to work with, its very versatile, and its fairly cheap cut to use. So much to love! It is super nutrient dense, too, what with 24 grams of high quality protein. Plus a standard 3-oz serving has over 10% of your daily intake for iron, zinc, Vitamin B6, Vitamin B12, Niacin, Riboflavin, choline, Selenium and Phosphorous.
Seriously, you get your money worth with this cut! To learn even more about the awesome nutrition packed into a flank steak, check out this nutrition page from Iowa Beef !
Making sure my girls get the proper nutrition they need for their growing bodies and minds is so important to me, and I never have to question what they are eating when I serve this meal.
These Flank Steak Tacos can be made start –> finish in about 30 minutes! They are super easy to make, too! You literally need 3 bowls and a grill (or broiler).
