Remove from heat. Using a food processor or stick blender, blend sauce until almost smooth. Add juice and season with salt and pepper. Blend or process until combined.

- Boil, steam or microwave beans and sugar snaps until tender. Drain. Top chicken with pumpkin sauce and coriander. Season with salt and pepper. Serve with vegetables,lime cheeks and sprinkled with coriander.
TIPS: When cooking chicken without oil, try not to turn it too quickly. It should release quite easily from the pan when the first side has sealed. Sauce can be made up to 2 days ahead. Store in an airtight container in the fridge. Add it: Dash of chipotle hot sauce or Tabasco in Step 3. Swap it: Chicken for 4 x 100g lean beef fillet steaks.
