I thought I'd share a recipe I discovered a while back now and have made many times since - it's so easy as it's all made in one pan, can be as filling or as light as you like depending on what you have with it, and it's versatile as to what herbs/spices you fancy throwing in there. And it's vegetarian, so great for sharing amongst a group.
The main ingredients are eggs, peppers, onions and a tin of tomatoes - I tend to have these in anyway as usually they're the base of almost everything I eat (also on my summer to-do list: try out new foodie things!). Add in a sprinkle of oregano, some paprika, chilli powder, parmesan - whatever you have to hand or are in the mood for. To satisfy meat cravings, fry some bacon pieces or a couple of sausages (skins removed and meat chopped) along with the onions. Chorizo would also be brilliant in this.
If you're hungry, serve on top of a plate of pasta with garlic bread on the side. To enjoy it for lunch or as a lighter meal, make some couscous and salad to go with it. This would also make a good brunch with some warm, crusty bread.
