Prepare ingredients per instructions above.

Preheat the oven broiler.

Lightly toast the rolls on a baking sheet.

In a small bowl, stir together softened butter and grated garlic. Spread the garlic butter onto the insides of each toasted sub roll.

Heat half of the olive oil in a skillet over medium heat. Sauté the onions and bell peppers until golden brown and caramelized, about 5 minutes. Transfer to a plate and set aside.

Add the remaining olive oil to the skillet. Add the shaved steak in an even layer and let it brown undisturbed for 2 minutes. Sauté until fully cooked through and season with salt and black pepper to taste.

Divide the steak into portions in the skillet. Top each portion with cheese. Melt under the oven broiler.

Place each portion of steak into a roll. Cut in half if preferred.

Add the lemon slices to the sparkling water. Serve over ice, if desired.

Serve the cheesesteaks with carrot sticks, ranch dressing, and lemon sparkling water.
