Who’s got two thumbs and is starting Whole30 today? Raises both hands. Then lowers them to my face so I can cry tears of sorrow. As a proper send off for the next 30 days of eating anything that tastes good, and all forms of dairy – including , my life blood, cheese – I thought it best to go out in a blaze of cheesy glory. How is that for self-sabotaging? And now you see why I’m doing this Whole30 thing…

But let me tell you – this was a send off worthy of the name. And wearing my stretchy pants for.

As a food blogger, it seems entirely counter productive to throw myself into a diet that “restricts” some of the fundamental food groups that help me survive day to day… chocolate, dairy, cheese, legumes? I mean, I’m all for cutting out everything but protein, veggies, and fruit – but legumes? No hummus? The horror! That is the point Ben even went “nuh uh”, tapping out.

Now, I’ve done these elimination diet kind of things before – and yes, I know they work, at one point I lost 22 pounds, it was great. And then I succombed to peer pressure and ate ice cream, drank bourbon, and like magic, it all game back. And then I graduated college, and well, never looked back. Because, bourbon… cheese, carbs, chocolate, and every other magic concoction under the sun. But now, it’s time to get back on the wagon. Knowingly coming up on this made me want to basically binge on everything that I was going to be missing out on, so this was my last meal, so to speak.

I’ve had friends ask if I’m going to be recounting my days on Whole30 here on the blog – and that only seems fair. I put every other embarrassing event here on the blog, so why should this miss out on all the fun? The plus side is that I have already found a Whole30 approved coffee creamer, so rest assured, no one will die today because I had to drink my coffee black.

Praise. And praise sirloin steak. At least I still have that beefy beauty in my Whole30 corner.

As with all diets, accountability is the hardest part – so please feel free to tweet me, Facebook me, or whatever it is you have to do to help get through your New Years Resolutions!! We’re in this together… missing carbs.

  • Total Time: 50 minutes
  • Yield: 12 1x
  • Category: Appetizer
  • Method: Ove
  • Cuisine: American


  • 1 pound Sirloin Steak
  • Salt and Pepper
  • 6 Tbsp Butter, divided
  • 2 Tbps Olive Oil
  • 2 Stalks Green Onion
  • 1/2 cup Mayonnaise
  • 4 ounces Pepper Jack, shredded
  • 4 ounces Parmesan, shredded
  • 4 ounces Cheddar, shredded
  • 1 Green Bell Pepper, diced
  • 1 Onion, thinly sliced
  • 1 loaf French Bread


Preheat oven to 350 degrees. As oven preheats, let steak rest out on the counter. Season with salt and pepper.

In one oven proof skillet, heated over medium heat, melt 2 tablespoons of butter, and olive oil until shimmering. Add in steak and allow to sear until dark brown on one side- approximately 4 minutes. Do not lift the steak out until it releases naturally from the pan. Flip steak and sear another 4 minutes. Place whole skillet with steak, into the oven all bake for 12-15 minutes, or until the steak registers 145 degrees. Set steak aside to rest when done.

While the steak is searing, heat additional skillet and melt remaining butter. Add in thinly sliced onion and caramelize onion until just turning golden brown. Add in green bell pepper to the onion mixture and continue to caramelize onion under deep golden brown.

When steak has rested, cut into small bite sized cubes. In a large bowl, mix together all cheeses, mayonnaise, green onion, and caramelized onion, bell pepper, and steak. Mix together throughly.

Slice french bread in half lengthwise. Place onto baking sheet. Divide mixture, and place on cut sides of bread evenly. Bake for 20-25 minutes, or until the cheese is completely melted. Remove from oven and let rest for 3-4 minutes, then slice and serve.
