For ourselves, we'd always have a seafood BBQ breakfast. Scallops in shell, green prawns, 'best of the day' fish fillets, all grilled, with simple sliced tomato & cucumber. Champers & OJ, chilled, went down a treat!
If the meal is for Lunch or Dinner, have you thought of a Salmon Kedgeree?
Tinned red salmon, deboned, cooked rice, or mashed potato, corn kernels, champignons pieces & stems, grated carrot, small pieces of celery, chopped parsley, fish stock,enough for moisture, sprinkling of lemon pepper seasoning, & Tabasco Sauce, if liked. Any other ingredients you fancy, could be added.
Mix all ingredients together, slice thickly enough tomatoes to top. Lid, or alfoil on top, pop in moderate oven 40-60 minutes. Once cooked, sprinkle your preferred type of cheese, & pop under griller, til cheese browned.
This us very filling, & most enjoyable, as it's different.
There's no need to serve anything with this dish, as all is in it! But if wanted, maybe cooled, sliced cucumber would be good.
It's a dish that you can 'do what YOU want with it'.
The most important item to have is the liquid fish stock, or vegetable stock, or a mixture of both, so that dish is quite moist, 'cos if it's too dry once cooked, not very nice to eat.
Weather would depend to cook this on the day. Not good in 35-40 degree heat!
Enjoy whatever you have!
