Learn how to make a delicious flank steak tacos recipe with avocado crema, cilantro and a chili lime rub for quick and easy weeknight dinners for taco Tuesday. (It’s also a great way to use that overabundant supply of zucchini July through August when your garden is overflowing!)

Meat is expensive, especially steak. I've tried meatless Mondays for dinner, however men don't seem to approve of this idea. After a long day of manual labor, it can be hard to fill their bellies despite high iron and protein content found in the farro and quinoa I like to sneak in.

On the flip side, ground beef for tacos constantly can be boring. Therefore, if you want to use red meat, I highly recommend flank steak. It's ridiculously cheap compared to a ribeye or a filet and makes a great alternative to a steak dinner. Plus flank steak is super versatile. I love it for tacos as well as other dishes.

For this taco recipe, I decided to use flank steak in lieu of ground beef. something other than ground beef. I also used lots of zucchini from the garden along with a divine avocado crema to top it all off. I winged this flank steak taco recipe, however I was pretty impressed with how my “winging it” turned out.

Therefore I thought I’d share my flank steak taco recipe so you can enjoy it on your next taco Tuesday dinner night.
