We generally go for green salads as a side (as OH doesn't like tomatoes) We use lettuce (usually little gem, round or curly or a bag of mixed rockets, watercress and baby spinach). To that we just add cucumber and sometimes spring onions, then dress with an olive oil and balsamic or flavoured vinegar dressing (or just add lashings of heinz salad cream if we're being lazy - can you guess which one we have most often )
But I used to love my old pasta salad recipe (which I never get to make any more - OH is so fussy)
Cooked cooled pasta (spirals are great)
cubed cucumber
tinned sweetcorn (the sweetened variety)
grated carrot
sliced raw closed cup mushrooms
snipped up spring onions
salt
pepper
a pinch of dried mixed herbs
a great dollop of light mayonnaise
stir it all up.
It was about 40-50% pasta, 50-60% veg with pretty much equal quantities of all veg (except the spring onions which were just a scattering to taste)
I loved it with garlic bread and quiche, or even just on its own with some grated cheese stirred in and crunchy croutons on top.
