Mumbai toastie from Diana Henry's Simple. Recipe available online at this link.
The bread is spread with a fresh green chile/cilantro/mint/garlic chutney, topped with Cheddar cheese, tomato, red onion and a pinch each of cumin, coriander, ginger and cinnamon before cooking in a sandwich press (which I lack) or under a weight.
I wasn't sure I'd like it but after gobbling this down, I found myself wishing there was more.
