Add the chicken stock, white wine and Parmesan rind. Bring to a gentle boil and let simmer for about 10 or so minutes. Add the tomatoes and thyme and bring back to a simmer. After about 20 or 30 minutes add the greens and stir them in. Add the peas. When the greens are wilted and the peas are bright green, serve hot.
Notes
If you're not going to serve it right away, wait until the last minute to add the peas, otherwise they get tired looking.
