I made this as a quick lunch yesterday so it was thrown together so I have no precise measurements.
I roasted the haddock with bit of salt and pepper with a squeeze of fresh lemon juice.
I roasted the vegetables with Italian seasoning and cooked until soft.
I boiled the cabbage, I served it al dente.
I mixed the passata with Italian seasoning and warmed in the microwave.
To serve I placed the haddock on a bed of cabbage, placed the roasted vegetable around the side, drizzled the sauce and crumbled the feta over the top.
