Heat up your waffle iron to medium-high heat. (Link in NOTES to the ceramic iron I used.)
Gently mix all ingredients (except extra oil for greasing) in medium bowl until well combined. (I like to use a meat chopper tool for this step…it helps save my fingernails from getting meat underneath.)
Use a silicone brush to lightly grease the iron with a dab of oil.
Depending on the size of your iron, add 1/2 to 1/3 cup of meat mixture at a time to iron, spreading it out evenly with a silicone spatula.
Close iron, then cook about 7 minutes or until crisped and fully cooked through.
For AIP: Serve with a drizzle of maple syrup if desired, or slather with a bit of No-Mess No-Egg Mayo (recipe in NOTES) and top with sliced raw veggies.
For Whole30: Slather with 100% berry preserves, almond butter or sunflower butter, or top with mayo and lettuce for a quick compliant sandwich.
