If you're unable to find gluten free and vegan breadcrumbs, you can substitute for gluten free oats or quinoa flakes.
If you are unable to find a vegan egg replacer, you can use flax meal or flax "eggs."





Vegan recipes with a focus on good feelin’, sometimes, but not always healthy, scrumptious comfort food. Most people don’t think of delicious comfort food when they hear the word vegan and I’m here to change all that! My name is Ashley, a vegan food blogger and recipe developer. While my wife and I develop recipes that range from quick and healthy, to deep-fried and salted, we specifically focus on good feelin’, sometimes not always healthy, scrumptious comfort food. Grab a drink and let’s have some fun in the kitchen!
