Here's a recipe my dad uses for zucchini:
Cut zucchini into either circles or strips.
Cover a cooking sheet in tinfoil and lay down a layer of a mixture of olive oil, garlic salt, and ground cayenne pepper.
Lay zucchini onto tinfoil and then brush the same mixture onto the top of them.
Put into an oven at 350 degrees for about 30 minutes (more or less depending on your prefered texture).
It doesn't sound like much, but oh man, I've never liked zucchini more in my life!
