Use peaches that aren't superripe for this recipe so they'll hold their shape when cooked. The baking dish will be brimming with fruit and topping, so it's a good idea to place it on a foil-lined baking sheet before putting it in the oven.
When my children were young, I made this onedish meal with frozen veggies and a more traditional pie crust. As they became more adventurous eaters, I added more dark leafy greens, and eventually exchanged the crust for this hearty wholegrain topping.
