Hi!
I think the longer you do the plan you will find your tastes do change. Its taken me since march but I have realised that I can say no to things a lot easier or choose a healthier option. Im lucky that I love most fruit and veg but I do get sick of eating it.
If you like curry you could try the 3 tin curry baked beans, mushy peas and chopped tomatoes add curry spices, cook it, blend it and add whatever you like to it (chicken, beef, prawns quorn etc.)
How about homemade soup? always a great full of veg filler. You could even add pease pudding and bacon so it tastes meaty? Or add cream cheese and stir through so its nice and creamy.
Casserole is always a great one too, instead of just stock/gravy use chopped toms and a stock cube for the sauce and then add any veg you like.
Pasta like spag bol as mentioned, and curries can have loads of 'hidden' veg. Chopped toms, grated carrot, shredded spinach, even adding things like onion, mushroom (which gets lost in dishes like these) spring onion, garlic etc will count. Try adding lemon or lime to water or diet pops, that will count too.
If you like baked beans, what not try adding some salad leaves and stirring them through, it almost gets lost but it will count towards your SF.
For fruit I swear by asda frozen summer fruit berries. I leave them to defrost in the fridge so I can pick at them whenever I like. I use them to top weetabix, porridge, yogurts and scan bran cakes. Yogurts with alpen light bars crumbled in them are lovely, it acts like a kind of granola and 2 count as your hexB. Aldi do some lovely bars that count as your hexB too but they have a different consistency and are better used for dunking in a cuppa, they go kind of gooey and cakey.
I really hope you can find something that works for you.
