Like so many of you – we’re still cooking our way through this summer’s bountiful harvest of garden-grown zucchini. But Jack and I are not at all complaining! Zucchini’s mild taste makes it a perfect, healthy ingredient in savory dishes (see here, here and here), and it’s equally terrific in sweeter, baked recipes (like this or this) as well!
