Squash & Zucchini are amazing in so many recipes. Want a quick curry? Squash + veggies + spices & rice. Want to thicken up a big soup? Add zucchini and let it cook down into nothing but added flavor and thickness.
And if you want to go another route, you can make any vegetable into wine.
I blame cheap carbs and lack of education around cooking; we need to bring back Home Economics classes and teach the new generation.
