1. Start the day before – soak the beans in a lot of cold water overnight.
2. About 1 hour before needing to serve, drain the beans. Put them in a large pot of water, along with the thyme, parsley, potato and tomato. Bring to the boil. Simmer for about 40 minutes – or until the beans are just tender. Note: cooking time depends on the beans you are using – great northern is about 40 minutes.
3. Prepare the scallops: Pat them dry with paper towel and season both sides with salt and pepper.
4. Scorch the chili in a pan over a gas (or electric) burner, until the skin is blistering.
5. Wash and coarsely chop the frisée. Finely slice the chili, removing the seeds if you wish.
6. Make a quick dressing for the beans: Place almost all of the lemon juice in a small bowl; add 3 times its volume of olive oil. Whisk to combine.
7. When the beans are done, drain them and discard the potato, tomato and herbs.
8. Heat a heavy bottomed sauté pan until hot. Add olive oil; when nearly smoking, add in a few scallops. Sear for no more than one minute, then flip. Cook for another minute. Remove scallops from the pan and keep warm.
9. Repeat with the remaining scallops. Remove the scallops from the pan and add in the remaining lemon juice and sliced chili. Shake together for 30 seconds.
10. Toss the frisée with the beans. Season with a little salt and pepper. Pour over some of the dressing and toss. Taste the beans and frisée. Add more dressing as required.
11. Divide the greens and beans between two plates. Pour over the pan juices and chili. Top with the scallops and enjoy immediately.
