A simple thing as tinned mackerel filets is a great source of protein in a salad. Especially if you don't use the tomato sauce, since that can be a bit high in carbs.
For this plate of deliciousness I used:
baby swiss chard/mangold leaves
avocado
eggs
tinned mackerel in tomato sauce
cherry tomatoes
cucumber
bell pepper
sunflower sprouts
mayonaisse
and some olive oil
Simple food for sunny days!
