Sometimes I like to have a very simple meal of rice and one dish, but more often I like to have a variety of differnet dishes, particularly vegetables.
It's obviously impractical to cook 5 or six dihes just for one or two people, so the technique I use now is to make a large batch of each dish and freeze portions in those non-stick 'muffin' tins you can buy (they are a little deeper than the 'fairy cake' ones.
Once the food is frozen, you can decant it into plasitc freezer bags, either having a bag for each dish, or making up meals by adding a 'lump' of each dish to a bag.
Then, when you fancy 'an Indian', you just place them around the edge of a plate and microwave. Add rice in the middle, and you have a fairly complex meal in around 15 mins.
Since no curry I have ever tried has been damaged by freezing, this is an excellent way to enjoy really good food even when you have little time for preparation.
