Hi alley22 I've already probably said this info several times over but if you're like me it's really difficult finding all the threads.
If you contact Wysoy they'll send you a little booklet with meals & some simple cake recipes using soy. I'm not sure but you could just substitute in some recipes though. I know I've got recipes somewhere for cakes using oil or prunes instead of fat. If I find the brownies one I'll try to post it here - it's delicious. If you let me kow I'll dig out the wysoy recipes for you they're quite simple ones
For sandwiches
I also give my ds pate - if you check the ingredients they often have no diary - lidl do a very good coarse and a smooth liver pate. I also make dried apricot puree (just apricots and tiny amount of water) if you keep it in the freezer it still spreads from the freezer. You can also buy cream cheese substitutes, cheese substitutes and alternative butter spreads from most health food shops. But always check the ingredients regardless. Often olive oil spreads in supermarkets contain diary. You can also buy lots of different nut or fruit spreads (or make your own). I also make chicken sandwiches (beware of supermarkets again some put milk in their chicken slices)
You can also make jellies and put fruit in (either normal if you don't mind gelatine, or ypu can use arrowroot or agar agar)
Sticks or cubes of veg or fruit, bread, cheese sub, cherry toms can be dipped in cream cheese sub or humous or a tomato based dip.
I've also found that my ds quite likes roasted veg can be served hot or cold with or without dips or on bread.
Strips of fish or chicken lightly coated in breadcrumbs.
If you really want to go town Jamie Oliver has a great recipes for sweets made from dried fruits roasted in the oven. They're really nice.
Provamel or silken tofu can be served with different flavours or you can by flvaoured ones. There is a chocolate flavoured provamel, but the vanilla one is really nice on it's own or over fruit or pudding. Sojasun (from health food shops) also does some really lovely desserts (which I love just as much as my ds) the lemon flavour is scrummy.
If you want to give 'milky drinks you can also use the more liquid provamel of yofu or silken tofu.
Hope you have a lovely time.
