Prawns stirfried just with some root ginger slices and chopped spring onions, serve with rice.
Artichokes!!!! Fantastic. Basically boil them and make a hollondaise sauce, or just melted butter, but hollandaise is better. This recipe isn't too badly done if you ignore about 90% of what's on the page and just focus on the bit about actually making the sauce.
Tomato salad - slice, sprinkle with chopped fresh herbs (ideally basil but whatever you have that is fresh will be nice), sprinkle generously with some oil and vinegar or whatever dressing you like, leave for a while in the fridge or just eat it fresh. Make a separate green salad by washing the lettuce (properly, wash each leaf), then put into a teatowel, hold the corners and whizz it round outside to get rid of the extra water, then dress it using your clean hands to make sure the leaves are coated. Fantastic with chicken.
Spinach is great just washed as a green salad vegetable. The basic principle of cooking it is to wash the leaves, shake a little, then put into a big pan with a cover while it is still wet and heat until it has wilted - it shrinks a lot. You can do that by putting it into a stew or soup as well.
Kohlrabi - I never found a recipe I liked very much for this so usually ended up just chopping it and putting some into a stew. I tried a recipe for it baked with cheese once, that was awful.
