Preheat the oven to 190 degrees Celsius.
Add the butternut squash/pumpkin, cherry tomatoes, sliced courgette and sliced peppers to a large roasting tray and spread them out evenly in one layer. Try not to overcrowd the veg as they will steam rather than roast.
Season with salt, pepper and mixed herbs.
Spray well with one kcal spray and bake them for 15 minutes turning them half way through and spraying again with one kcal spray as needed.
Meanwhile, spray another lined tray with one kcal spray and add your basa fillets.
Rub each fillet with the grated garlic and season with salt and pepper.
Pour lemon juice evenly over each fillet.
Place the fish in the oven alongside the veg and bake for a further 15 minutes until the fish starts to flake
The veg may need to be turned from time to time.
Serve each basa fillet with a quarter of the roasted veg and a lemon wedge.
