I quite often eat breakfast and luch at my desk (I teach in an FE college - although we have lunch breaks these are often spent marking/ planning lessons/ sorting out problems etc). For breakfast I either have a shape yogurt, fruit and an Alpen Light bar, a smoothie made with frozen berries (Sainsburys do a bag in their basics range which is only £1), a bannana and some VLF greek yogurt, which I take to work in a travel mug.
Lunch is either leftovers from the night before plus salad, couscous made at work (just need a kettle and a bowl) and salad or SW quiche, which I throw together before I go to bed and put it the combination oven to cook (I can set a time limit and the oven turns it self off) and just chop it up in the morning and stick in a container with (yes, you've guessed!) salad. Tomorrow I will be having homemade dal and rice (with salad) as I am cooking it for tea tonight. I don't mind eating it cold.
I always make sure I have fruit (normally grapes and apples) in my desk drawer and I take a yogurt and Alpen bar in most days in case of nibbles. I also have a jar of mint Options for those moments when I need a bit of comfort - but I have to make sure it stays well hidden or else my colleagues will use it all up.
Although it sounds a bit boring having salad everyday it really isn't as you can ring the changes - on a Sunday I use my food processor to grate up a load of carrots, which I keep in a Lakeland stayfresh bag. I also make a bean salad (mixed cooked beans, loads of apple, celery, spring onions and a strong hm vinegarette) plus lots of bits and pieces in the fridge. I just have to grab what I want the night before and spoon it or do a minmal bit of choppingto have a tasty salad. (I normally make a tzatziki, on a Sunday, with VLF greek yougurt, chopped cucumber and/ or spring onions, mint and salt (no garlic as I teach 1-2-1 or in small groups and am careful not to have smelly breath!) to act as a salad dressing).
I love couscous, especially when it's cold outside, as you can have a warm and tasty meal for no bother!
