I know it can be hard to find the time. But really, sauces needn't take long, and a lot of the time you don't even have to prepare in advance. For example, whilst my grain is cooking I chop up my veg and saute in coconut oil (use meat too if you eat it), and then I will make a sauce right there in the pan, maybe a drizzle of honey, splash of red wine, tsp mustard, herbs & spices, and there you have a very simple but tasty sauce! I mix it up, so maybe I add peanut butter one day, or pureed tomatoes another day, splash of balsamic vinegar... Just make it up and you'll create some marvellous flavours!
