Soak the onions in almond milk and flax eggs in a shallow baking dish preferably overnight (or at least 4-6 hours). The longer you soak, the more the breading will still to the onions.
When ready to make the onion rings, preheat the oven to 450 degrees.
In a large plate or shallow dish, mix the flour, breadcrumbs, panko breadcrumbs, italian seasoning, garlic powder, and salt.
Line a baking sheet with parchment paper. Remove each onion ring from the milk and coat with the breadcrumb mix, pressing the onion down into the mix to cover completely. Place each onion ring on the baking sheet.
Spray the onion rings lightly with olive oil. Then, sprinkle with smoked paprika.
Bake for 15 minutes at 450 degrees. Remove from oven, turn onions over, spray lightly with olive oil and bake for about 10-15 minutes more, until crispy and brown on both sides. *Baking times may vary.
To make the Spicy Mayo, mix Vegannaise (or other non-dairy mayonnaise) with the Sriracha. Dip the onion rings in the spicy mayo or ketchup.
