Heat the oil in a saucepan.
Cook the onions in the oil until translucent, then pour in the mild curry powder, turmeric, thyme and pepper flakes.
Stir continuously for about 30 secs, then add the chopped tomatoes.
Continue to stir for around three minutes, then add enough water to cook the oats (based on cooking instructions on the rolled oats packaging). Cover the pan and allow the liquid to boil over for 2 mins.
Pour in the oats, add some salt to taste and allow to cook for between 5-10 mins until the oats cook through.
Stir in the spinach and remove from heat.
