In the fridge I keep baby toms, cucumber, avocados, salad leaves, packs cooked beetroot (not very low carb).
In the larder we have dried dates, prunes, apricots, goji, figs, cherries. (Not vlc but very small quantities).
Also walnuts, pecans, almonds, pine nuts, anchovies, olives.
Protein sources are eggs, smoked salmon, ham, garlic sausage, goat's cheese, tinned tuna.
I mix and match from the above to make the salads.
Our local Lidl is getting very good at organic fruit and veg. The nearest proper shops are a 30km round trip so we keep masses of stuff in stock and always shop with a list!
We limit the smoked meat to once a week. At the moment our not salad days (!) are devoted to eating up last year's minestrone made from our own vegetables.
