Cut cabbage into bite-sized pieces, slice onion into 5mm wedges, thinly slice garlic and remove its core, and cut bacon into 1.5cm strips.

Boil water in a pot, add salt (not listed in ingredients) and spaghetti, and cook 1 minute less than the package instructions. Reserve 50ml of pasta water and drain the spaghetti.

Heat olive oil, garlic, and chili peppers in a frying pan over low heat until garlic turns golden brown. Add bacon and cook until browned, then add cabbage and onion, stir-frying over medium heat until slightly softened. Add scallops and stir briefly.
