The Modern Nonna

0 Add the ground meat to a large bowl. Add in the egg, salt to taste, the oregano, black pepper, garlic, breadcrumbs, and dill. Mix well with clean hands. Add in the feta and mix again. 
1 Cover the meat mixture and let it set in the fridge. This step is needed so the meat can firm up. I leave it in the fridge for about 1 hour but you can also do this overnight. 
2 When the meat has set, remove it from the fridge and divide it into 4 equal balls. Flatten each ball into a disc, making sure it's even all through out. 
3 Gently press down the middle of each patty (this helps them cook evenly).
4 Preheat the barbecue to 450F (making sure to oil the grill) and cook the patties for 7 to 8 minutes on each side or until the burgers reach an internal temperature of 165F. I like to open and close the lid to check on them every 2 minutes. 
5 Note: You can make them in the air fryer or on the stovetop, in a pan, as well.  
6 When the burgers are done, enjoy them as-is with sides such as steamed rice, raw, grilled, or roasted veggies, salads, dips, etc. or in between a burger bun with your favorite toppings. 
7 I added tzatziki to my bun with pickled onions and lettuce but feel free to use anything you like. Enjoy!
