I'm new to BLW myself but I have a few meals we can all eat and are easy for LO to hold and self-feed, not sure about DS's allergies though.
Roast chicken thighs with rosemary potatoes, apple and pumpkin - this one is great because you season and then just stick all the ingredients together in a oven dish and go do something more interesting than cooking;)
Fish baked in tin foil with cauliflower cheese
Spaghetti Bol - but here I'd be careful about the tomatoes, maybe use other veg that are less acidic instead. The pasta makes a crazy mess but DD loved it
French toast for breakfast
Pumpkin fritters (2 cups mashed pumpkin, 2 cups flour, 2 eggs, 3 tsp baking powder, curry or cinnamon, bit of salt - drop them in a pan with olive oil and fry till golden brown) DD had them plain, we put garlic sauce on ours. They are supposed to be a but mushy inside so don't worry that they are not cooked through. I think you could probably substitute the pumpkin for zucchini and it should work too.
Beef burgers - DD got a bit of bun, a bit of the burger, some cheese, cucumber and mashed them all up on her tray herself;)
Rice noodles with chicken, zucchini, carrot and green bean stir-fry (added soy sauce after taking out DD's portion
That's all we've tried so far. I'm trying to introduce food more or less in the order suggested by the wholsomebabyfood site just in case, so our ingredients are still pretty limited.
