Bring to a boil a saucepan of water with the herbs.
Pat dry the chicken breasts and place in boiling water. Make sure they are completely submerged. Cover pan, remove from heat and set aside for 25 minutes or up to an hour.
While the chicken is poaching, prep and cook the other ingredients for the broth.Add olive oil and the sliced garlic to a cold 8” inch pan and heat on medium/low fire. When the garlic starts to sizzle, sauté and stir for a couple of minutes to flavour the oil. Once the garlic releases it’s flavour (you can tell by the aroma), add chili flakes and cook for a further minute stirring often. Remove the pan from the heat and over the sink, add the tomatoes. They will splatter when they hit the hot oil. Once they have settled down, put them back on a the fire. Let them stew and release their liquid - about 2 minutes.
Add the water, wine, oregano, and thyme and raise the heat to medium high. Simmer the tomatoes for about 10 minutes to reduce the liquid. Press down on the tomatoes with a wooden spoon a few times to help break them down to form a chunky broth. Taste and season with salt as needed. Add a little water if broth looks a little dry and turn down heat to a low simmer.
Test chicken for doneness by gently piercing with a fork to see if juices run clear. If you have a temperature gauge, the internal temperature should read 165F 74C.
Place chicken on a cutting board and cut them across into 3/4 " slices.
Put chicken slices into the simmering broth for about a minute to warm them up. Add a little water if broth looks dry.
With a soup spoon, pour some broth and tomatoes in the base of a shallow bowl (or dinner plate) and top with chicken slices. Drizzle a little broth on the chicken.
Garnish with chopped oregano and lemon wedges and serve with slices of grilled ciabatta or baguette bread.
For more substance, serve a little cooked farro on the side in a separate small plate. You could add a little farro to the broth so it absorbs the flavor.
