Notes:
1. Adjusting Spice Levels: If you prefer a milder taco, omit or reduce the jalapeño in the green sauce and adjust the chilli powder in the beef filling.
2. Cheese Variations: Feel free to substitute the cheddar and mozzarella with your favourite cheese blend for a different flavour profile.
3. Green Sauce Prep: Make the green sauce ahead of time and store it in the fridge to let the flavours meld together. It can be kept for up to a week.
4. Customisation: Add your favourite toppings like shredded lettuce, diced tomatoes, or sour cream for extra flair!
