Ingredients

• 1 pound ribeye steak
• 1 teaspoon sea salt
• 0.5 teaspoon freshly ground black pepper
• 0.5 teaspoon smoked paprika
• 0.5 teaspoon garlic powder
• 2 tablespoons olive oil
• 8 romaine lettuce leaves
• 1 small red onion
• 1 large tomato
• 1 avocado
• 2 tablespoons Whole30 compliant mayonnaise
• 1 tablespoon Dijon mustard
• 1 teaspoon fresh lemon juice

Directions

Step 1

Take the ribeye steak out of the fridge and let it come to room temperature, about 15 minutes.

Step 2

In a small bowl, mix together sea salt, black pepper, smoked paprika, and garlic powder. Season the steak on both sides with this spice mixture.

Step 3

Heat olive oil in a skillet over medium-high heat. Once hot, add the steak and sear for about 4-5 minutes on each side for medium-rare, or to your desired doneness.

Step 4

While the steak is cooking, prepare the vegetables. Slice the red onion thinly. Slice the tomato and avocado as well.

Step 5

Remove the steak from the skillet and let it rest for about 5 minutes on a cutting board.

Step 6

In a small bowl, combine Whole30 compliant mayonnaise, Dijon mustard, and fresh lemon juice. Stir until well combined to make a dressing.

Step 7

Cut the rested steak into thin slices against the grain.

Step 8

To assemble the sandwiches, lay two romaine lettuce leaves flat as a base for each sandwich.

Step 9

Spread a small amount of the mayo-mustard dressing onto the lettuce leaves.

Step 10

Layer slices of steak on top of the lettuce, followed by red onion, tomato, and avocado slices.

Step 11

Drizzle a little more of the dressing over the top if desired, and then top each with two more lettuce leaves.

Step 12

Serve immediately and enjoy your Whole30 Classic Steak Sandwich!
