Grilled mackerel. Fillet, bought frozen, defrosted and patted dry, grilled on a piece of foil, skin-side down first then turned to crisp the skin. (Note that “grilled” in UK English means the heat comes from above.)
Mashed potatoes. Peeled, cubed potatoes, boiled until soft, mashed with Eastern European-style sour cream.
Caponata. Made with courgettes and cherry tomatoes instead of my usual aubergines and tinned tomatoes, hence more watery/saucy than usual. This came from the freezer too; it was a spare portion I froze a while ago.
