Delicious, the two green apples in the burger patty made it so moist and tasty. I'm not usually a fan of fennel but I liked it in these burgers. Also threw in some garlic and finely diced green onion to the burger patty, plus an egg to help it all bind. I made a quick homemade apple sauce in the microwave (literally just peel two apples, I used one red and one green, cut them into cubes and microwave for 4 mins and then mash it with a fork into a tasty sauce). The burger, with the apple sauce and some quick fried red onion, (and lettuce for crunch) was AMAZING - highly recommend
