- Marinate tempeh overnight for deeper flavour if you have time.
- Use multi-coloured bell peppers for visual appeal and antioxidant variety.
- Crisp the tempeh slightly in the pan to mimic grilled meat texture.
- Add avocado or guacamole for extra creaminess and healthy fats.
- Choose low-carb tortillas or lettuce wraps for a lower glycemic option.
