Yummy! I used red onion and red bell pepper, zucchini, white cornmeal and everything else according to the recipe. I used freshly made horseradish sauce from Fresh Horseradish Sauce. The vegetables were all wonderful and crisp tender. I thought the horseradish would have more of a presence but it was more of a background flavor enhancer. This was also very colorful...beautiful! I will be making this again! Thanks for the recipe.
