Buckle up and get ready for a pretty epic Whole30/Keto/Gluten Free/Paleo sandwich. It’s Whole30 Flank Steak BLT made with grass fed flank steak, nitrate and sugar free bacon, smashed avocado, ranch, and hollowed out heads of iceberg lettuce. Trust your friend Laura — You won’t even miss the bread!
How the Flank Steak BLT went down:
Husband: What should we have for lunch?
Me, rifling through the fridge: We have nothing in the house. We have steak and bacon, and compliant mayo though…. OH MY GOODNESS I have an idea!!!
Sometimes it’s as simple as that! I had everything I need to make a BLT except one thing, bread. I had iceberg lettuce, and I’ve used iceberg to make lettuce wrap before (that’s actually the main reason I even buy it)… but I’m still a bread girl at heart.
So I just needed to get my mind in a new place and be creative. I’m trying to up my protein game too, and I had just gotten a delivery of grass fed beef, so I thought, ooh okay, let’s do this!
And the most super ultimate sandwich of all time was born.
What you need
- Flank Steak. You can substitute skirt steak, because they’re generally interchangeable in recipes like this.
- Tomatoes: I prefer BIG beefy summer tomatoes.
- Iceberg Lettuce
- Ranch for those following Whole30, Bleu cheese for those following Keto, or Mayo. Use whichever you have and whichever you prefer.
WARNING: This sandwich gets messy
Just a quick note to self: Keep a fork & knife nearby when you eat this, and a few napkins too! Because the lettuce wrap is in place of bread, it becomes a drippy mess pretty quickly… and you know what? I’m 100% okay with that.
In fact, I think it’s even better when your sandwich is a little messy.
All the delicious goodness making a little mess on my plate, well – it’s part of the fun! You know what I’m talking about, right?
