Chicken, bacon, spring onion, brie, mozerella, sweetcorn
Then I normally try and add in some veg that might not be as enjoyable like brocolli or cabbage but their flavours will be hidden by all the other nice things and some salt and pepper.
Omlettes are just something that I feel are really nutritious and I feel full afterwards. It's good proteins plus the veg and a small portion of cheese 10-25 grams is not much but makes it more enjoyable.
Because I have a great not stick omlette pan and a easy to wash electric whisk it's a really easy dish to do.
Basically I want something easy, nutritious and not too long to make that I can just through ingredients and flavour into.
