Toast bread: Cut the ciabatta rolls in half horizontally, then spread the inside of each with softened butter. Toast them under the broiler, in a toaster oven, or in a skillet over medium-high heat. Get them nice and golden brown!

Notes

Tri Tip Notes:

This Smoked Tri Tip is my go-to recipe, but these sandwiches are good with any grilled tri tip recipe. Use your favorite or choose a pre-marinated tri tip from the store. I have good luck at Costco and Sam's for both plain and marinated tri tip.

Tips & Tricks

Make sure to slice the flank steak very thinly against the grain for tender pieces that are easy to eat.
Toast the buns. Don’t skip it. Warm, toasty bread makes the sandwich.
If using leftover tri tip, be careful not to overheat it so that it doesn’t dry out.

How to reheat leftover tri tip:

To reheat sliced tri tip, cover it in a damp paper towel to retain moisture. Reheat in the microwave on medium power in 20 second increments, or until just warmed through. Don’t overheat it or it won’t be juicy and tender.
