Flavorful. I added Chili Powder, Garlic Powder, Cumin. and since people were having trouble keeping together I added flour, bread crumbs and Panko then I baked 25 min at 350 I baked on a silicone sheet Nice and compact. I didn't want to open a jar of Salsa for such a small amount so I mixed ketchup, water, chili powder and part of a crumbled chipolte boullion cube.
Really good flavors! I had a little trouble keeping them together, but we had no problem eating them with a fork and knife :) I had some leftover avocado, so I added a few slices on each burger. Thanks for sharing!
