Peel the grapefruit making sure you removed all the zest.
Cut in half horizontally. Using a spoon gently separate the flesh from the pith.
Cut into cutlets shapes and set aside
Boil enough water to cover all the cutlets. Simmer for 5 minutes.
Drain and rinse under cold water. Using your palms, squeeze the cutlets and place on a clean towel.
Marinade
Heat up 1.5 cups of water, add 2 tbsp of vegetable broth (Better than Bouillon Chick'n flavor is best for this recipe but other brands will do too).
Add 1 tsp of Dijon mustard, 1 tsp garlic powder and some pepper.
Dip each cutlet in the marinade and set it aside for 5-10 minutes.
Squeeze the marinade out by hand and pat dry.
Make the batter
Mix 2 tbsp dry egg replacer with 4 tbsp warm water and stir.
Add salt, pepper, and turmeric
Season the breadcrumbs
Mix 1.5 cup of panko bread crumbs with 1 tsp garlic powder, 1 cup finely chopped parsley, salt and pepper
Putting it together
Dip each cutlet in the liquid egg replacer, shake off the excess, then dip in the seasoned breadcrumbs.
If you are baking them, place each cutlet on a baking sheet making sure they don't overlap, spray with a little oil. Bake at 375F for 15 minutes flipping them half way through.
If you are air frying them, spray some oil and fry for 16 minutes.
If you are deep frying, make sure the oil is heated at 325 F so that they can crisp (less than a minute per cutlet). Work quickly as they can burn fast.
Place on a paper towel to drain excess oil. Serve hot with your favorite dip or sauce.
Notes
Add some beet powder to make something more beefy, add some old Bay seasoning and dill to make some fish patties. You get the idea. Have fun experimenting!
