TBH I do cariations on a theme!!
I have a 'mediteraenan' casserole with passata, loads of herbs, garlic, peppers, courgettes etc
A 'moroccan' one with a great spice mix called Ras al Halout (A Nigella tip) cinnamon, palm syrup, and sweet potatos, butternut squash, parsnips, carrots all cut into batons.
Others include curries, chillis, etc. All with a base of onions, leeks, passata, and then chilli, curry or whatever spices.
Have a look for this brand when out and about. They have FAB mixes
