A solution to the revision-lunch conundrum

I rarely ever eat lunch that doesn't involve some form of cooking - normally it's something like roasted veg and couscous salad with feta/goat's cheese, or eggs on toast with smoked salmon, or noodles, or carrot salad with feta and coriander, or a vat of soup that I've been organised enough to make in advance. But at the moment, what with my Finals starting in a week, I'm too busy to do a lot of cooking in the middle of the day. At the same time, I don't really like the idea of living off bought baguettes, or expensive pre-prepared salads from the supermarket. Out of the blue, I came up with the best solution EVER this morning - smoked mackerel pâté. Not only does it take about five minutes to make and then will last me for the rest of the week, it also has mackerel in it, i.e. oily fish, i.e. BRAIN FOOD. I could not have thought of a better idea had I tried. I fully expect a starred First now as a result of excessive mackerel consumption.
So, it's just a tub of cream cheese, some chopped parsley, the zest and juice of a lemon, salt and pepper, a teaspoon or so of creamed horseradish, and about 300g smoked mackerel fillets. The mackerel was £3 and I got four quite big fillets - I am always astonished by how cheap it is. Smoked mackerel is even more divine than fresh mackerel in this case, and the whole thing is delicious. Incredibly rich though, so I didn't need much at all. Lovely on toasted seeded bagels. I also reckon it would be nice with apple chutney to take away some of the richness, which I intend to try tomorrow. It'll probably last me until Finals start...and then I'm going to make some more, but with smoked trout this time. Or smoked haddock. I think this is the start of a pâté craze.
