Some veggies should never be put in the fridge if you want to keep peak flavour. Here are the ones that I know of.
1. Tomatoes, the cold robs them of taste and texture.
2. Onions, The cold makes the onions produce sugars reducing the flavour.
3. Cucumbers, The cold makes them start to break down becoming acidic and reduceing flavour, the cold simulates what happens in the garden in fall.
4. while oranges can be ok in the fridge for some reason [I don't know] Limes and Lemons do not, they lose flavor rapidly.
