In the pot, heat up the broth. Then slice the seitan and blanch it in the boling broth for 10-15 minutes. Drain the seitan but don't throw away the broth (you may need it later).
Add the flour onto the plate and start flouring each slice of seitan, on both sides.
Zest and squeeze the lemons, then leave them apart.
Heat 4/5 Tbsp of oil in the pan, then add the garlic cloves (peeled) and some sage leaves (save a few for the garnish). Allow to flavour for about 1 minute.
Now add the seitan, the lemon juice and the zest (save some of the latter for garnish). Add salt and pepper to taste and let it cook for 5-10 minutes. If needed, add some broth. The final result should be a creamy and soft seitan.
Garnish with the remaning zest and sage leaves. Serve warm. Enjoy! 😋
