I didn't do much cooking - heated up two pies for myself and the wife, and a pasta meal for the daughter.
I did make my own mashed potato as mine is much better, much cheaper and much lower in salt than the pre-made stuff.
I do the same with new potatoes - can't bear those dismal microwave packets. Just chuck the new potatoes in a pan - chop in half if a bit big, boil em up, drain - chuck in some mixed herbs, chopped fresh basil and oregano if i have it, otherwise the dried stuff, a good knob of butter and one turn of table salt from the grinder. Lid on the pan. Agitate the spuds for 30 seconds. Pour onto plates. Lovely - potatoes are nicely coated in herbs and butter.
