Stuffed portobello mushrooms - using up breadcrumbs and leftovers

This is my entry for this month's no waste food challenge which for my May is bread. This is my suggestion for using up stale bread and breadcrumbs. It also ended up being a really good way to use lots of leftover bits in the fridge. A leftover tomato, bit of goats cheese and rocket. I have listed my ingredients below but be very flexible with this recipe and just use what you find.

---

• 2 Portobello mushrooms
  
• 1 slices tomato
• handful of rocket
• bit of lemon rind
• sliced spring onion
• breadcrumbs
• leftover goat's cheese
• little bit of grated mature cheddar

1. I started by slicing the spring onions and adding these to the mushroom with a knob of butter and a sprinkle of lemon zest. I then layered the tomato, goat's cheese and rocket. 
   
2. Mix the bread crumbs with the grated cheese and arrange on top.
3. Grill for 5-10 mins until cooked and the cheese is bubbling.

These are delicious especially as the butter melts down into the mushroom and the lemon zest really lifts the flavours. Enjoy!
