Hi there,
Dd hates broccoli but will eat it sometimes if it's mixed with other things. She LOVES avocado!! I mix it with yogurt sometimes too and she gobbles it up. (I don't really like it myself either but it's easy to make!) We've used leek as well mixed with other veggies. One recipe we did is parsnip, carrot and poached chicken blended together and frozen, and another was broccoli, zucchini and parsnip steamed, pureed and then frozen.
