what i did when i was on it was make a massive amount of whatever i was cooking and then stored the leftovers. unfortunately, the time to cook the stuff is necessary but it is worth it.
heres some staples that i frequently had:
-homemade yogurt
-homemade applesauce
-roasted veggies (any kind of veggies you like, olive oil salt and pepper, oven, delicious)
-have cooked chicken on hand, theres a lot you can do with that--chicken salad, chicken omelette with veggies, etc
-OHH one of my faves! a salad of: lettuce, carrots, olives, warm chicken breast with cheese, a bit of homemade mayo if you have it, and oil and vinegar. SO GOOD and pretty quick and easy if you have everything on hand.
-the pizza recipie in the book is AWESOME. i still make it and im not on the diet anymore hahah, i reccomend toppings of bacon, montery jack cheese, and parm.
-most grocery stores carry a large selection of frozen fruit. thats a good thing to have on hand too....make smootihes with the yogurt and some honey.
-this recipie is actually for a weight loss diet but is totally acceptable for the SCD and tastes really good:
http://allrecipes.com//Recipe/vegetable-quiche-cups-to-go/Detail.aspx, just use realy eggs in place of the egg substiute and i put extra bacon and cheese in mine hahah.
-burgers are always a good meal, just buy the ground beef and make your own patty with cheese of your choice and veggies of your choice.
is there Trader Joe's in the UK? i feel there probably isnt but thats where i did much of my shopping when i was on the SCD. its basically a grocery store that focuses on organic and natural and such. and while not everything in there is SCD legal, you can find some great stuff that is because they make and carry many products that dont contain extra sugar and corn syrup and such. good place to look for salad dressings, tomato sauces, premade soups, and other prepared things like that.
really though, no matter where you shop you just gotta look at the ingredient list carefully. its a pain but once you find those products that are perfect? then your shopping is a breeze.
until you can find those convenience products that suit though, i would just focus on buying fresh and whole foods. veggies, meats, fruits, etc. and making you own sauces and condiments to make these foods a bit more exciting.
oh and soup! make your own chicken soup, thats always an awesome staple as well. or whatever kind of soup you like.
do you shop online? i have a collection of links to online SCD stores that are great, they sell premade legal baked goods and nut flours and great stuff, but i dont think they are viable cuz youre in the uk lol but i will give them to you if you want! lemme know. but i just found them by searching online, search SCD buy food, SCD store, all kinds of stuff and im sure theres some great UK based stores as well.
i definitly did not go hungry once i figured out how to have quantities of acceptable foods lying around. you actually have options and its pretty awesome! i actually have made myself really hungry typing this hahah so i mean its food you WANT to eat not just your only choice.
the worst for me was cravings for all your pre diet favorites. i cheated very often haha, i was terrible at sticking to it perfectly. unfortunately no matter what kind of nut flour you use, you just cannot make an oreo =/
