Choosing Your Protein: Meat & Vegetarian Options

Fajitas are incredibly versatile when it comes to protein. Here are some healthy options:

Lean Meats

• Chicken breast: High in protein and low in fat. Marinate for flavour and grill or pan-fry.
• Turkey breast: Similar to chicken but with a slightly richer taste.
• Beef strips: Choose lean cuts like sirloin or flank steak. Trim visible fat before cooking.
• Prawns: Quick to cook and rich in omega-3 fatty acids.
  

Vegetarian Alternatives

• Halloumi: A firm cheese that grills beautifully. Use sparingly due to its salt content.
• Tofu: Absorbs marinades well and crisps up nicely in a griddle pan.
• Tempeh: Nutty and firm, great for slicing into strips.
• Beans: Black beans or kidney beans add fibre and protein. Use as a filling or side.
  

Veggie Power: Best Vegetables for Fajitas

Vegetables are the heart of healthy fajitas. They add colour, crunch, and essential nutrients.

Classic Veg

• Bell peppers: Red, yellow, and green – all add sweetness and crunch.
• Red onions: Slightly sweet when cooked, perfect for caramelising.
• Tomatoes: Use fresh or make a salsa.
  

Additional Veg

• Courgettes: Mild flavour and great texture.
• Mushrooms: Add umami and bulk.
• Carrots: Thinly sliced or grated for crunch.
• Sweetcorn: Adds sweetness and colour.
• Aubergine: Charred for a smoky flavour.
  

Fresh Toppings

• Avocado: Sliced or mashed for healthy fats.
• Lettuce or rocket: Adds freshness.
• Red cabbage: Crunchy and colourful.
• Cucumber: Cooling contrast to spicy fillings.
  

Cooking Methods: Griddle Pan, Oven & More

Griddle Pan

A griddle pan is ideal for fajitas. It gives meat and veg those signature char lines and smoky flavour.

Tips:

• Preheat the pan until very hot.
• Use minimal oil – a spray or teaspoon is enough.
• Don’t overcrowd the pan; cook in batches if needed.
• Press ingredients gently to maximise contact with the ridges.
  

Oven Roasting

Great for meal prepping large batches.

How to:

• Toss meat and veg in marinade.
• Spread on a baking tray.
• Roast at 200°C (fan) for 20–25 minutes, turning halfway.
  

 

Stir-Frying

Quick and easy, especially for tofu or prawns.

How to:

• Use a non-stick wok or frying pan.
• Cook meat first, then add veg.
• Stir constantly to avoid burning.
  

 

Healthy Seasoning & Marinades

• 1 tsp smoked paprika
