While some people yearn for bread, carbs, and sugar, I dream of juicy steak, plump shrimp, and salmon sashimi. You show me a meat and cheese platter and I’m a happy girl.

When it comes to serving high protein, low carb meals for my family, there is nothing quite like lean cuts of meat.

In fact, whenever I make flank steak I like to make extra to use throughout the week in sandwiches, salads, tacos, and more. Spoiler alert: I may have an idea for turning this beautiful steak into tacos – coming soon!

Frequently asked questions:

Can I cook steak on the stove and get the same taste as the grille?

Yes. If you don’t have a grill available you can broil in the oven on high heat for 4-5 minutes per side or until it reaches desired doneness.

Do you taste the coffee in the steak rub?

No. You hardly taste it.

Your fork is waiting.
