Preheat oven to 375 degrees.
Combine egg, turkey, salt, pepper, and onion in large bowl and mix together. Make patties into flattened balls using about 1/4 c of meat.
Place patties on a greased, foil-lined pan. Place in oven for 25-30 minutes, keeping an eye on them to make sure they aren’t under or over done.
Cut pretzel buns in half. Spread a generous amount of peanut butter on the top bun, and a heaping spoonful of fig jam on the bottom.
In large pan, cook bacon to desired texture—soft or crispy.
When burgers are done, remove from oven, place on pretzel bun and layer bacon, lettuce, tomato, and any other toppings.
