Some lunch ideas 

Wholemeal pitta with:

• Tuna and salad
• Avocado and salad (I add nut and seeds for some crunch!)
• Hummus and salad
• Chicken and salad (I always cook a chicken on Sunday for lunches during the week)

Omlettes : ( Get creative) 

• Salmon, turkey, bacon or chicken
• Mushrooms and tomatoes, onions
• Basil, cinnamon
