Veggie Cottage Pie with Garlic Butter Sweet Potato Mash

Before 2017 came to an end, I decided that I was going to try and go meat free. There was so many factors that went into the decision, ethical reasons, health reasons, environmental reasons, but it was time to mix it up.

Cottage pie is such a hearty and filling meal, and making a vegetarian one seemed like a great idea. Also the added flavours of garlic butter and sweet potato really make this dish something special.

This dish is packed full of vegetables and makes a lot of servings so its perfect for making on a Sunday ready for the week ahead. The fact that most of the ingredients can already be found in the kitchen too is a huge bonus.

My favourite thing about this recipe is that I got to add cheese to it! There is nothing better than garlicky sweet potato mash topped with cheese! I added protein cheese to up the protein in this recipe (girl needs her gains).

So without further ado, here is the recipe:
