Ingredients:
-
1 lb shaved roast beef (ask the deli counter for thin-sliced, nitrate-free beef)
-
4 whole wheat or sprouted sandwich buns
-
4 slices Swiss or provolone cheese
-
1 tbsp avocado oil or butter
-
Salt and pepper to taste
For the clean “Arby’s-style” sauce:
-
¼ cup ketchup (no sugar added)
-
1 tbsp horseradish (prepared, not cream-style)
-
1 tsp apple cider vinegar
-
½ tsp garlic powder
-
½ tsp smoked paprika
-
Dash of salt
Instructions:
-
Make the sauce
In a small bowl, whisk together ketchup, horseradish, vinegar, garlic powder, smoked paprika, and a pinch of salt. Set aside. -
Warm the beef
Heat a skillet over medium heat. Add shaved beef and a splash of water or broth. Cover and steam for 2–3 minutes until heated through. Season lightly with salt and pepper. -
Toast the buns
Spread a little avocado oil or butter on the buns and toast cut-side down in a skillet until golden. -
Assemble the sandwiches
Layer warm roast beef on the bottom bun, top with a slice of cheese, then drizzle with the homemade sauce. Add the top bun and press gently. -
Serve warm
Serve with sweet potato fries, a simple green salad, or roasted veggies.
Sarah’s Tips:
-
Make it dairy-free: Skip the cheese or use your favorite plant-based option.
-
Need gluten-free? Swap in a GF bun or lettuce wrap.
-
Make it a melt: Toast assembled sandwiches in a pan or panini press for a few extra minutes.
-
Meal prep tip: Keep beef and sauce separate until ready to serve for the best texture.
