A tit tonne of salt, thickener of some kind, herbs, dried tomato powder, that kinda thing. I’ve used a sachet once in my life, never ever again. Tasted like tit. It’s really not difficult to chuck together a casserole, bolognaise, cottage pie etc etc like you say...What is in a casserole sachet? I’ve never used one. I’m making a casserole tonighr and it’s just stock, tomato purée and Worcestershire sauce, plus veg and meat. Not sure what time she is saving?!
