Ooh, we have recently been through a hellish veg refusal stage - even the ubiquitous Red Pasta Sauce (you know, the grate up 5 types of veg and blend it with passata, garlic etc) was refused. But my success has been veg bhajis/pakoras, she adores them.
Bhajis:
Pulse together in a food processor half an onion onion, a smattering of frozen peas and a small handful of baby spinach (you could hack it all up by hand but I cba) until its very finely chopped.
Grate half a carrot.
Combine all veg in a bowl. Add a load of gram flour (ground chickpeas), and spices. I added 1/2 tsp ground cumin, 1/2 tsp ground coriander, 1/2 tsp garam masala and a little sprinkling of cayenne pepper.
Mix the spices and gram flour round the veg until everything is well coated (add more gram flour if you need it).
Then add milk (or water, but I figured milk is extra protein), mixing, until you have a fairly stiff batter.
You can also mix in some sesame seeds or similar if you feel they need the extra oils/protein.
Then pour enough oil into a small frying pan to cover the base of it.
Heat the oil
Drop teaspoons of the mix into the hot oil, squidge them flattish, and fry for a couple of mins each side until dark golden and crispy.
Drain on kitchen paper.
For toddlers, let them cool before eating (they willl be very hot inside)
For adults, salt generously and scoff while hot. They are fab before/alongside a curry.
The mix above does me, DH and DD.
You can obv vary the veg, but the onion is key so don't skip that. Sweet potato, broccoli stalks grate in very well. You could add frozen corn/broad beans. Or mini cauliflower florets. Whatever really.
The creamy sauce I described earlier is also very good with prawns. For those I would start with the onion/garlic, but not add flour, would crumble in a tiny bit of stock cube instead, add a small splash of boiling water to dissolve the stock cube and help the prawns cook through, then when the water is reduced to almost nothing, stir in cream and add a small amount of grated parmesan. It's yum with spaghetti.
