Black Bean & Portobello Mushroom Burger With Castello Blue & Red Onion Marmalade

Instructions

1. For the burger patty, chop the mushrooms into small chunks (around 1-inch pieces), place in a tray and season with olive oil & salt.
2. Bake at 180 degrees for 20 minutes, until the moisture from the mushrooms has evaporated. Once baked set aside and allow to cool.
3. Once cooled mix the mushrooms, mashed black beans, diced red onion, Dijon mustard, breadcrumbs, cream cheese & egg, combining ingredients until the mixture is bound together.
4. Use this mix to mould into patties (the mix will make between 6-8 patties).
5. Pan fry the patties in a little oil, to colour on each side, then cook in the oven for 6-8 minutes to order.
6. To make the red onion marmalade, place sliced onions in a pan then add all other ingredients and cover pan.
7. Slowly simmer until onions have lost all water, reducing until you’re left with a jammy texture. Allow to cool fully before using.
8. For the burger build, toast the burger bun and spread a spoonful of onion marmalade across the bottom of the bun.
9. Add a Castello Blue Cheese Slice on top of burger patty and place under the grill to warm the cheese up.
10. Place patty with melted cheese on top of red onion marmalade.
11. Add a little salad (rocket or gem) and some Dijon mayonnaise to finish.
