15-Minute Roast Beef and Feta Sandwiches

Mediterranean-inspired sandwiches layered with tender roast beef, tangy feta cheese, and peppery arugula, by a creamy tahini dressing and vibrant roasted red pepper mixture. The combination of fresh herbs, cumin, and garlic creates bold flavors that meld beautifully during chilling. Perfect for lunch gatherings, picnics, or meal prep, these substantial sandwiches benefit from resting time that allows the tahini dressing to soak into the ciabatta while the flavors marry together.

FAQ
Can I make these sandwiches without chilling?
While you can serve immediately, chilling for at least 2 hours allows the tahini dressing to soften the bread and flavors to meld together much better.
What if I don't have tahini?
You can substitute with hummus for similar consistency, or make a simple lemon-garlic yogurt dressing as an alternative.
How long will these sandwiches keep?
Wrapped tightly, they'll stay fresh in the refrigerator for up to 2 days, though they're best within 24 hours.
