I adopted this recipe in September 2006, selecting it because I love healthy side dishes that add flavor to the plate. the original chef commented that the recipe is from Robert Del Grande.

We loved this recipe. Super easy and the red onions have a nice kick to them. I chose to add the red pepper flakes, the fennel seeds and the dried oregano - I believe these spices make the recipe such a success.

These have a wonderful inviting aroma while cooking and the taste does not disappoint. I had considered leaving off the fennel and decided against it and am glad I did. The fennel does add that extra something. The blending of seasonings is wonderful. These would be a great companion to almost any meal.

The fennel flavor is certainly 'assertive' as noted by Geema. I served them on top of a hamburger and it was good. For me, next time I'll add more garlic and skip the fennel.
