White Bean and Fish Gratin


White Bean and Fish Gratin
this easy fish gratin uses frozen fish and vegetables.
Each serving provides: 17.5g protein, 18.6g carbohydrate (of which 5.9g sugars),
 7.9g fat (of which 1.7g saturates), 8.5g fibre and 0.74g salt.

Ingredients
Serves Six - adjust menu to suit
2 tbsp olive oil, plus extra for drizzling
350g/12oz leek, roughly sliced
300g/10½oz celeriac, cut into 1cm/½in cubes
400g tin white beans (butter beans), drained and rinsed
1 vegetable stock cube
3 tbsp dried mixed herbs
1 tbsp fennel seeds (optional)
½ tbsp cornflour (or plain flour)
400g/14oz frozen mixed vegetables
300g/10½oz frozen white fish (thawed), cut into thick chunks
50g/1¾oz day-old bread, crackers or mixed nuts, roughly blended into crumbs
salt and freshly ground black pepper

Method
1. Heat the oil in a large casserole over a medium heat and add the leek and celeriac. Season with salt and pepper, put the lid on and cook for 7–8 minutes until softened.
2. Meanwhile, place half of the beans in a small blender with 300ml/10fl oz hot water.
3. Add the vegetable stock cube and blitz. The mixture should be fairly loose. Add the mixed herbs, fennel seeds (if using) and blended bean mixture to the leek mixture and bring to a gentle simmer. Stir in the cornflour to thicken the mixture.
4. Add the mixed vegetables, fish chunks and remaining beans and cover with a lid for another 5–8 minutes to cook through. At this point, preheat a grill to medium–high. Remove the lid of the casserole and scatter with the crumbs. Drizzle with olive oil, sprinkle with some salt and pop under the grill for 2–3 minutes until golden and bubbling. Remove from the heat and leave to stand for a few minutes before serving.

Recipe tips
You can swap out some of these ingredients if preferred. For celeriac, you can also use parsnip, sweet potato or turnip. For white fish, use prawns, tuna or more white beans to make it vegetarian. Instead of frozen mixed vegetables, use broad beans, peas or frozen green beans. 
Note: Any swaps will not necessarily provide the nutritional detail as shown below image.

  9. Hmmmm. Despite I do not like fish, this sounds "acceptable"! My Mom made fish patties - soooo good, sadly I do not have the recipe. I will try this soon (I hope... fish is really... difficult for me - I blame my Dad, it´s in the genes).
