Veggie burgers are pretty popular these days. This recipe is an oldie from the 70’s, slightly revamped. Nutty oat burgers on portobello caps.
Back in the late 70’s and early 80’s we were pseudo vegetarians. Pseudo because we’d occasionally eat seafood and sometimes chicken. One thing that we had a lot were these nutty oat burgers. We usually had them on a bun with ketchup and mustard. I decided to cut down on the carbs and have them open-faced on a baked portobello mushroom cap. There’re as tasty as I remembered and this time served with a mayonnaise, ketchup and mustard sauce.
All you do to make these is throw all the ingredients into a bowl and mix them up. I let the mixture sit for about 10 minutes before I make the patties to let all the moisture get absorbed by the oats.
I made 4 large patties from one recipe, but you could make 6 smaller ones if you’d like, or even make appetizer sized portions. You could serve them with a little sauce on top with a slice of pickle stuck on with a toothpick! Yum.
Our kids always liked these. Oat burgers made a quick lunch that they never grew tired of.
This is certainly a recipe to keep handy if you’re into a vegetarian diet.
