Chop the onion and red bell pepper. Place ⅓ c of each onto a microwaveable or paper plate and microwave on high for 60 - 90 sec on high. You are looking for the veggies to be tender. Set aside.
Place the ground turkey, cooked onion and bell pepper, panko breadcrumbs, garlic powder, dried oregano, dried dill, black pepper and salt into a bowl. Use your hands to combine them all together.
Add the egg white to the meat mixture and use your hands to incorporate the egg white into the meat mixture. Pinch off a piece of the meat mixture about the size of a quarter and flatten it out on a napkin. Microwave on high for 25 sec. Let it briefly cool and taste it. Adjust the spices if you think it is necessary to suit your taste.
Use a medium size cookie scooper to portion out the meat mixture into a baking pan. My medium scooper portioned out a meatball that weighted 0.9 oz.
Once you are done portioning out the meat mixture, go back and roll each portion into a meatball. Spread the meatballs out in the baking pan. Add a thin layer of water to the bottom of the pan. It will facilitate cooking and keep the meatballs moist.
Cover the baking pan with aluminum foil. Place in the oven and bake at 350℉ for 25 - 30 min depending on your oven. You are looking for them to be cooked through out. If you are using a meat thermometer, you want them to be 165 - 170° on the inside.
Remove the meatballs from the oven when done and transfer them to a sheet pan ( I used a pizza pan) covered with paper towels to blot away the moisture.
Transfer the meatballs to a plate and serve as an appetizer with some tzatziki or use as an ingredient in another dish.
Place any unused meatballs into a plastic freezer bag and store in the freezer until you need them. They freeze and reheat well.
Notes
In this recipe I used store bought panko breadcrumbs. 1/2 c of the panko crumbs were 3 pt. An equivalent amount of my homemade breadcrumbs were also 3 pt. The only advantage of using homemade crumbs over the panko would have been an increased amount of fiber from the low carb bread I use.
