I just have a quick and easy recipe today. There's a bit more calories than I would like, because of the avocado. But it makes a great lunch.
Just peel and cube up an avocado. Chop 2 or 3 small tomatoes, and seed them. (I've learned that I like tomatoes so much more without the slimy seeds!) Add half a chopped Valencia onion. Sprinkle with a little seasoning salt. (I actually use a salt substitute - just whatever flavors you like) and add a couple of tablespoons of balsamic vinegar.
I make this up the night before so that it's all ready to take with me to work for lunch the next day. Easy, delicious, plus it's good for you!
