Herby pasta. Just a big handful of mixed fresh herbs of your choice stirred into a few tablespoons of good olive oil, then mix into hot pasta (linguine, spaghetti or angel hair is lovely) with some salt & pepper. Lush, quick lunch.
Quesadilla. Top flour tortillas with grated cheese, finely chopped tomato, pepper and onion, some jalapenos and a dollop of tomato or corn salsa - you can add coked chicken, chorizo, prawns or whatever if you want. Fold in half, press down and fry for a minute or two each side.
Poached eggs w/ streaky bacon or pancetta & asaparagus
Grown up fishfinger sandwiches. Coat white fish in flour and fry up. Serve with crusty white bread & butter and a wedge of lemon.
Super quick Thai beef (DH loves this). Fry up some thinly cut steak in oil (peanut oil best) for a minute, then add crushed garlic and finely chopped fresh red chilli. Turn steak over and fry for another minute. Then add a big handful of basil leaves, 4 tablespoons of water and a good splash of soy sauce. Fry for a further 90 secs then dress with lime juice and chilli flakes and serve with white rice.
