Vegan Deviled "Eggs" (uses vegan mayo) - these have an actual egg taste thanks to a special seasoning salt easily found online, and a firm, egg-like texture thanks to agar agar powder. I pretty much gotta try this.
These vegan egg substitutions work especially well when needing structure/texture in baking. For leavening, try touch extra baking powder or baking powder + an acid (ex: lemon juice or vinegar). plant based, whole foods
