Charred broad beans & peas with feta, mint & olives

Ingredients
1 small cucumber
2 handfulls of broad beans, freshly podded
2 handfulls of peas (fresh or frozen)
small handfull of mint
a few olives, sliced
half a block of feta, crumbled
2 spring onions, sliced
juice of half a lemon (and zest)
Olive oil
salt & pepper
Method
Get a large frying pan to a med- high heat, with a little oil to coat the base.
Throw your bread beans in and toss them occasionally, so they get browned on both sides. Add the peas after a few minutes and continue to toss.
Meanwhile, make a bed of lettuce on a big serving dish.
Once the beans and peas are cooked to your liking (just give them a taste if you're not sure), transfer into a bowl and add the lemon juice and a drizzle of olive oil. Stir in all the other ingredients (except the lettuce) and season with salt & pepper
Pile the bean & pea mixture on top of the lettuce and serve.
