Nice one Iain. I haven't had salmorejo, will have to see if I can find a recipe and try it. For putting on bread or toast, we normally do pan tomaca, which isn't really a recipe, you just rub or smush a tomato onto the bread or toast, and drizzle olive oil and sprinkle with salt. Here we tend to use baguette or sourdough.
Her gazpacho is good - especially as it's a heatwave down here at the moment with 30°C indoors. But as you say, the simplest dishes are the hardest to get right, and with UK supermarket produce, very difficult. How on earth did they convince us that appearance was more important than flavour? We rarely manage to get it to taste as good as in Spain because of the UK tomatoes, although if we can find those big ones in a proper market we use those.
When we were still able to travel back and forth to Spain before Covid she used to bring back olive oil! You can of course get Spanish olive oil here but not the one she liked. Although she says most olive oil sold as "Italian" at a premium was actually produced in Spain and bottled in Italy.
