Add your butter to a saucepan and melt over a low heat. Add the finely sliced leeks, sliced garlic, thyme and diced rosemary.
Cook for about 8 - 10 minutes until the leeks are soft and fragrant. Add your wine, and cook for another couple of minutes.
Tip in the beans, veggie stock, seasoning, and cheddar cheese and stir. Cook for a further 8 - 10 minutes.
Grate over the pecorino, add more seasoning to taste, the lemon juice and zest, and scatter over your parsley.
Serve with crispy bread and enjoy!
