### Simple Roast Beef Sandwich Recipe
This is a quick and easy roast beef sandwich that's perfect for lunch. It serves 1, but you can scale it up. Total time: about 10 minutes.
#### Ingredients:
- 2 slices of bread (e.g., sourdough, rye, or your favorite sandwich bread)
- 4-6 thin slices of deli roast beef (about 4 oz)
- 1-2 slices of cheese (like provolone, Swiss, or cheddar)
- 1 tablespoon mayonnaise or mustard (or both for a combo spread)
- Optional add-ins: Lettuce leaves, tomato slices, red onion slices, horseradish sauce for extra kick, or pickles
#### Instructions:
1. **Prep the bread**: Toast the bread slices lightly if you prefer a crunchier sandwich (optional, but recommended).
2. **Assemble the base**: Spread mayonnaise and/or mustard on one or both slices of bread.
3. **Layer the fillings**: On one slice, add the roast beef slices, then top with cheese. If using, layer on lettuce, tomato, onion, or other veggies.
4. **Finish and serve**: Top with the second slice of bread. Cut in half if desired, and enjoy immediately. Pair it with chips or a side salad for a full meal.
Tips: For a warm version, microwave the assembled sandwich for 20-30 seconds to melt the cheese. If you want to make your own roast beef, that's a separate recipe, but deli-style works great for simplicity! Adjust seasonings to taste.
