This was my son’s go-to snack. Cooking a large batch up on Monday, he had a bowl-full at snack time or with his meals if I was in a lazy mood. There are no right and wrong combinations of vegetables - just use what you have in your kitchen, or what is in season.
If you serve the stored herby vegetables straight from the fridge from day one your baby will have not trouble with the cold herby vegetables. (Make things as easy on yourself as you can from day one!)
