280 ml Milk

35 g Mozzarella
240 g Macaroni (uncooked)
0.5 whole Lime (juiced)

Steps

Chicken Marinade

1

In a bowl, combine the cubed chicken breast with 1.5 batches of the fajita seasoning mix, olive oil, and the juice of 1 lime. Mix until fully coated.

Tip: Mix until you lose patience — the longer it marinates the better, but even a quick coat works well.

~5 min
2

Cook the marinated chicken in light butter over medium-high heat for 6 to 8 minutes until golden brown. Set the cooked chicken aside.

Tip: Avoid overcrowding the pan so the chicken browns rather than steams.

~8 min

Fajita Mac n Cheese

1

Cook the macaroni according to package instructions until al dente. Drain and set aside.

~10 min
2

In the same pan, add the chopped white onion, red onion, red bell pepper, and green bell pepper. Sprinkle with additional fajita seasoning and cook over medium heat until softened.

Tip: Using the same pan keeps all the flavour from the chicken in the dish.

~5 min
3

Add the milk, light cream cheese, grated cheddar, and mozzarella to the pan with the vegetables. Stir continuously over medium heat until the sauce is creamy and fully melted.

Tip: Keep stirring to prevent the cheese from sticking to the bottom of the pan.

~4 min
4

Add the cooked macaroni to the cheesy sauce and stir to combine. Then add the cooked chicken and fold it in gently.

~2 min
5

Squeeze in half a lime juice, give the dish a final stir, and serve immediately.

Tip: The lime juice at the end brightens all the flavours — don't skip it.

~1 min

Fajita Seasoning Mix

1

Combine all Fajita Seasoning Mix ingredients — salt, oregano, garlic powder, onion powder, paprika, chilli powder, and cumin — and mix well. This makes 1 batch of seasoning.

Tip: Make extra batches and store in an airtight jar for future use.
