Recipe Comments & Reviews

Absolutely delicious! I cooked a couple time for breakfast. My husband was surprised at how meaty and satisfying these were. It can be use as replacement meal as meat. Thanks for sharing this great recipe.

I broiled - nowhere to cook outside. The recipe was easy to follow. Cooking was quick and the end result was a welcome change from everyday burgers (not that there is anything wrong with everyday burgers!) Just sometimes it is nice to have something different.
