Get your potatoes boiling (I leave the skin on and mash them up – think a lot of goodness is here – although I sound a bit like my Mum now…)
Meanwhile, chop up half a White Onion – into very small ‘dice’
Mix 2 tsp English Mustard with 1 tsp Dijon Mustard
Chop lots of Parsley
When the potatoes are cooked and soft to the point of a knife – mash them really carefully
Then add your Mustard, a good grind of Salt & Pepper and the chopped Onion
Mix together really well and just before serving, re-heat in a pan before adding the chopped Parsley (Chervil or Marjoram are also great herbs with potato)
