Caramelised Onion Mash

Today's mash post is one of Matt's. This was made to accompany some Fry's Pepper Steak pies. Wow, these pies are a revelation! They didn't look that exciting in the box, a little shallow and a lot more expensive than that other more widely available vegan meaty pie but they are so worth it. The sides are roasted parsnips, steamed spinach and leeks. The mash is swirled with caramelised onions and complemented the pies beautifully. I've never thought of putting onions into mash before, in gravy yes but mash no. It's a winner!
