How to choose the best zucchiniI tend to go for smaller zucchini (less than 8 inches long), as they have better flavor. Larger zucchini are more bitter the bigger they get.Choose firm zucchini, with a dark green color, with no cuts, bumps or blemishes.Store unwashed in the fridge, then rinse well before cutting and grilling.Substitutions/AdditionsYou can use Italian dressing instead of the olive oil/lime juice combination. Balsamic vinegar can replace the lime juice too, if you prefer!Switch the lime juice and zest for fresh lemon juice and lemon zest.Adding garlic powder, onion powder will give you a deeper flavor.Italian seasoning with lemon and olive oil is fantastic.Summer squash works very well for this, do a mixture of zucchini and yellow squash for a pretty color change!
