Quite simple lunches are any of Sunny’s soup recipes with a slice of low carb bread.
If you haven’t had egg for breakfast, 2 poached eggs on a slice of low carb bread is good too.
I sometimes have a tin of sardines or salmon with salad.
I invented low carb egg salad open sandwich today. Chop the egg up with light ricotta cheese instead of mayo. It held the egg together beautifully and I topped the egg with colourful veggies or you could add herbs.
