Are you a steak lover like we are? Our family adores steak, and lately we’ve been grilling more flank steak.

Balsamic Soy Steak Marinade

You may have already tried my Flank Steak Tacos (so easy). Flank steak costs a little more, but it’s so tender, and only takes a few minutes to marinate and cook!

It has the perfect flavor pairing to rich beefy steak. It’s incredibly easy to make, and most likely uses staple ingredients you have stocked in your pantry.

How to use leftover steak

Leftovers? We love to make a Caprese Steak Sandwich (just add steak to this Caprese Sandwich Sliders Recipe).

Or serve it on a summery strawberry salad!

Also, I’ve been thinking, with our current state of the world, how important it is to know what we believe right now. These crazy times can be so confusing, so how important is it now to truly decide how we want to think, to feel, and what we believe. How to be strong.

But more importantly, how do we show up? We can’t just cocoon and do nothing.

For me right now, in my small circle of friends, and my city, and world–feeding people is TRULY important for me. It’s a place to start.

Eating together

Eating together helps us dive deep into today. We talk about life, stand firm in our beliefs, listen and learn from others.

But our thoughts have consequences. And those consequences become our life. And today is the day that we live our life.

We live in a very serious time, another reason why we need fellowship and good recipes to share with one another!

ENJOY this steak! Definitely a must have recipe!

  • 1/4 c balsamic
  • 1/2 c soy sauce
  • 1/4 c coconut aminos
  • 1/4 brown sugar
