Preheat the oven to 350F/175C

Line a baking sheet with some parchment paper

Chop the bok choy in pieces, smaller pieces for the stalks as they take longer to cook.

Bake 10/15 min up until the salmon is fully cooked

Transfer in a food processor and blend up until smooth

Serve warm or refrigerate in an air tight container for up to 2/3 days or freeze for up to 3 months
