Vegan shepherd's pie

I always loved shepherd's pie as a kid. It's so warm and comforting. Try my low carb vegan version made with lentils instead of mince and cauliflower instead of mash. Delish!


1 head cauliflower

1/2 cup vegan butter, melted

1 red onion, diced

2 carrots, grated

1 1/2 cups frozen green peas
