Joe is also a fusspot when it comes to vegetables. He'll eat any fruit grown on the planet but veg? Evil!
So I often chuck 2 beaten eggs, whatever plain yoghurt or creme fraiche or ricotta I might have left lurking about, cheese, grated zucchini or pumpkin or cauliflower or any other veg into a bowl, whisk and pour into a shallow muffin tin, greased. 15 mins at 180C and they're done. They're good warm or cold. He eats those almost without fail.
Fishcakes are good, as are premade filled pasta which I get - veg or spinach versions - and serve with any type of pesto, like Aubergine or basil. Whatever, he'll eat that.
Seconding Bean's recommendations - we get 3 Little Dishes via our weekly Ocado order. He loves those, they're a good standby and actually really high quality. With some seasoning I'm happy to eat them! Best are the pasta ones, chicken & butternut risotto, lamb hotpot and pirk balks and beans.
And I'm not-as-ashamed-as-I-should-be to admit that his probably fave after pasta is the Sunday night special if posh fish fingers and not posh at all McCains Smiley Potato face things. Awful!
Obv anything on our plates he wants. As soon as it moves to his it becomes disgusting.
