A vegetable curry gets in a lot. (Designed for getting lots of veg in kid rather than authenticity)
Cauli, courgette, onion, carrot, sweet potato, butternut squash, tumeric, cumin, garlic, ginger, spinach, coriander, tomatoes, seeds:sesame, pumpkin, sunflower, chia, poppy. sometimes I put in chopped up Brussel sprouts) chick peas, peas
Veggie chilli with peppers, lentils, onions, kidney beans, black beans.
Fruity curry, (which is definitely get stuff in kid) has dates, apricots, sultanas, pineapple, apple, raisins hidden in it. Plus aubergine, and veg mentioned above.
Sweet and sour:carrots peppers, onions, mange-tout baby sweetcorn.
Stir fry:
Bean sprouts, Chinese stir-fry mix, (water chestnuts and bamboo shoots, a couple of leafy veg) carrots onions, mange-tout baby sweetcorn ,peppers, edamame beans,
Stews would be good too. . I'm going to read back others ideas too.
