Garlic prawns is one of the easiest and delicious things to cook and is something I have as much as I can afford to (and we - I don't eat any differently whether alone or if DP is here. I know this is a lighthearted thread, but I'm constantly astonished about threads like this, where it appears that so many women are cooking food that they don't want to eat themselves, that takes more effort than they want to make, to please their male partner. If he wants something big or faffy, he cooks it himself surely? If you want prawns, beans on toast, bits of cheese or gin and crisps, you just have it, and if you're feeling generous, you say 'I'm having beans on toast, do you want some? and he says yes or no. And if he says no, he sorts out what he wants himself?)
Anyway, back to the prawns. Olive oil in a frying pan, couple of tablespoons maybe, whatever you want to end up eating soaked into nice bread, medium heat, add some chopped garlic as much as you like, couple of cloves, fry for a bit until softened, then tip in as many prawns as you want to eat, fry for a couple of minutes until they look cooked. Add some smoked and/or hot paprika, maybe about half a teaspoon, stir and voila. If you like chilli, you could put some chilli in with the garlic. Eat with crusty bread.
If you have some tomatoes, maybe put some in with the garlic if you want some - if we have some cherry tomatoes that are a bit soft to go in a salad, but still OK cooked, it's a good way of using them up and allows you to pretend that it's healthy because its got veg in.
