Protein snack ideas?

I quite often have leftover bits of smoked bacon that have been fried up to be nice and crispy so one thing I like to do is top them off with a bit of strong cheese and then once it has gone cold cut it into squares and just bang them in a Tupperware dish kept in the fridge.
That way I can throw them over a nice mixed salad with feta cheese, roughly chopped eggs, half a handful of nuts and whatever else takes my fancy. It’s quick, simple tasty and nutritious and you can top it off with your favorite homemade mayonnaise or salad dressing.
Hope that helps,
Mark
