Greggs Cheese & Caramelised Onion Toastie
Caramelised onion chutney, sliced mature Cheddar cheese and red onion sandwiched between white bread made with sourdough, topped with béchamel sauce and grated mixed cheese. Guaranteed to be loved by dads, divas and Donna down the street – and all for a good reason.
Allergens: Soya, Wheat, Barley, Milk
About This Dish
The Greggs Cheese and Caramelised Onion Toastie costs £3.80 and presses 548 calories of melted cheese with sweet caramelised onion between toasted bread. The toastie is café comfort's final form, and Greggs sells it at a price the cafés stopped offering years ago.
The press does the magic: crisp shell, molten centre, the structural integrity a cold sandwich never achieves. The caramelised onion pushes it past the plain cheese version: sweetness against the sharp cheddar, and the vegetarian pick of the hot line.
It runs on the hot counter through lunch and afternoon. Tomato Soup at £3.15 beside it is winter's complete answer, and the hot line's baguettes cover bigger appetites. Live prices on the hot food menu.
