💡 Smart Nutritional Guidance
Consumption advice
Enjoy the grilled chicken and vegetables with a fork as a satisfying main course with just one small tortilla, or skip the bread completely and wrap the hot fajita filling in large, crisp lettuce leaves.
Best preparation methods
Ask for the chicken and vegetables to be cooked with a little olive oil rather than lots of refined commercial oil, and enjoy the grilled flavour and aromatic spices such as oregano and cumin.
Important Nutritional Note
Fajitas on their own are a great, favoured choice to support balanced blood sugar; what drives the rise in blood sugar is not what's in the pan but how many tortillas you eat with it.
