Luffa

Spaghetti Squash

Spaghetti Squash scores higher due to its broader culinary appeal as a low-carb staple and its beta-carotene content. Luffa is excellent but limited by availability and a specific safety caveat regarding bitterness.
You trade the satisfying, strand-like bite of Spaghetti Squash for the soft, sauce-soaking brilliance of Luffa.
