French Dip Beef & Onion Ciabattas

This is one of those fabulous meals that feels a little fancy but is SO easy, and perfect for a cosy night in. The Slow Cooker does all of the work of the work for us, and instant gravy means you get the perfect thick gravy without any hassle. The beef freezes brilliantly too so you can easily prep it ahead, just be sure to dunk the sandwiches in the extra gravy!
