Start a charcoal or gas grill to medium-high heat, or preheat your broiler and place the rack 3 to 4 inches from the heat source.
Ensure the seitan is patted thoroughly dry.
Cut it into large cubes, steaks, or leave in whole pieces.
Brush all sides generously with oil.
If using cubes, thread them onto skewers for easier handling.
Place the seitan pieces or skewers directly on the grill grate or under the broiler.
Cook for 3 to 5 minutes per side, brushing with more oil if needed, until lightly browned and slightly charred in spots. The total cooking time should be less than 10 minutes.
Remove from the heat and season with salt and pepper to taste.
Serve immediately as whole pieces, sliced, or allow to cool for later use in sandwiches or salads.
Threading seitan cubes onto skewers makes them much easier to flip and handle, especially on a grill.
Don't overcrowd the grill or broiler pan. Give the seitan pieces space to ensure they brown evenly on all sides.
