Place oatmeal in a blender and blend until it becomes a flour-like consistency.

Chop the carrot, beet, and potato into small pieces.

Boil the chopped vegetables until they are soft.

In a bowl, mix the oatmeal flour with garlic powder, onion powder, smoked paprika, and seasoning salt.

Drain the boiled vegetables and add liquid smoke.

Blend the vegetables with liquid smoke using a hand mixer until smooth.

Gradually add the dry ingredients (oatmeal flour and spices) to the blended vegetables, mixing well to combine.

Form the mixture into hot dog shapes.

Wrap each hot dog with plastic wrap and tie the ends securely.

Place the wrapped hot dogs in boiling water and cook for 25 minutes.

Remove the hot dogs from the boiling water and carefully unwrap them from the plastic wrap.

Fry the hot dogs in a frying pan until golden brown.

Serve the vegan hot dogs on buns with your favorite toppings.
