I'm a big fan of eating healthily. For lunch I'll generally bring in a tupperware of fun. For me a decent lunch is 1 or 2 chicken breasts, half an avocado, chopped vittoria tomatoes, spinach and brown rice. Tend to chop it all up and mix together. Dressingwise there are a few options. Sometimes a little extra virgin, honey, lea & perrins or hot sauce- always black pepper. Whatever I'm feeling like in the morning. The brown rice can be switched out for quinoa or cous cous.
One favourite of mine is a baked sweet potato with a whole tin of tuna mixed with gherkin, avocado and light mayo. Then some spinach and toms on the side.
Sometimes if I need a little boost I take on a spoonful of whole earth peanut butter- or have this on a cheeky slice of wholemeal.
Another nice little snack, and one I've found good for recovery is cottage cheese mixed with a chopped apple, cinnamon, mixed nuts and a little swirl of honey.
Really simple and quick things to do (aside from the baked sweet potato- they generally take 40mins) :-)
