This is an easy, sort of healthy meatless and adaptable recipe. I love it since it is quick but delicious. Especially good for damp, wintry nights. You can substitute any frozen veg you like - as long as it will poach without getting mushy and any herbs you like.
Peel, cook and mash potatoes or use a box of instant potatoes- yukon gold or other mildly flavored mix. Set aside
Season fillets with salt, pepper then poach in a skillet on the stovetop.Once the pan starts simmering, cover and poach about 4-5 mins,using both liquids and herbs ,peas and onions. Remove fish from liquid and flake, but save some of the poaching liquid. Remove peas and onions with a slotted spoon. Discard sprigs of herbs.
While poaching, preheat oven to 350.
Mix fish, peas, onions and some of the poaching liquid( 1-2 tbs.to make potatoes spreadable) with the mashed potatoes and spread in a glass pie plate or other oven-safe dish that is lightly greased. Drag a knife over the top of the potato mixture and dot with butter if you like. Bake @ 350 for about 20-25 mins until heated through and top is a little browned.
