Here’s how I make it:
Gently simmer some onion ( & occasionally garlic too) in a little olive oil for a couple a couple of minutes.
Add frozen peas, cover with boiling water, add some stock granules and bring to the boil.
Then add some fresh mint. After a minute or so whizz it up in a blender and season to taste if required.
That’s it! Mega simple, super healthy and really delicious. It also works great with some cooked ham chucked in too.
