I had a nuked Jacket potato today with sour cream some melted cheese and some bacon....mmmm was so tasty.

I have recently started making my own Sushi, as I am totally addicted to it- very delicious.
Another good one is some pasta, with either fresh or tinned tomatos, mushies etc maybe some bacon or ham and a sprinkling of cheese.
I love to make an omelette for lunch sometimes with heaps of stuff in it, mushrooms, tomato, spring onion.
DH makes a really nice dip that is sardines in Tom sauce, with a bit of extra tom sauce a finely diced red onion all mixed together, it is yummy on toast, or with veggies or rice crakers and very healthy too.
On the weekend we make up antipasto plates with whatever we have in the fridge, boiled eggs, tuna, cheese, ham, veggies etc- often we will buy a loaf of fresh bread for lunch ont he weekends too.
Something that you can make ahead of time is mini egg and bacon pies in muffin tins, and freeze them. They are so simple cut out some puff pastry to fit in your muffin tin, chop up some bacon and tom and onion, beat up the eggs with a little bit of water and some herbs, put it all into the pastry in the muffin tin and bake int he over to egg is set. Really yummy and healtheir than quiche.
