First, let's prepare the burger meat, in a bowl, add ground chicken, breadcrumbs, parmesan cheese, onion, garlic, sage, salt, black pepper, and 1 egg. Use your hand to mix all the ingredients.
Second, with this the meat is ready. Use a spoon to specify the amount for each burger. Then, make the meat flat to fry it.
Next, bring a pan, and put the flat meat in it. fry it for 3 minutes then flip it. Add one cheddar cheese above the flat meat and let it fry for another 3 minutes. Wait until the meat cooks well.
After that, bring the burger bread and divide it in half. Bring 1 avocado peel it and smash it with a fork. Put the smashed avocado in the burger bread.
Next, add salt and black pepper. Add the fried meat, tomato slices, and a layer of mayonnaise. With this our burger is ready. Cheers!!!
