Troubleshooting
Onions burned or too dark.
Reduce heat to low and stir more frequently; add a splash of water if they start to stick.
Patties are dry.
Do not over‑mix the meat mixture and avoid over‑cooking; keep grill heat medium‑high, not scorching.
Vegan cheese does not melt.
Cover the patty with a foil tent or a lid for an extra minute to trap steam.

Freezer: Patties can be frozen raw for up to 2 months; thaw before cooking.
