Ohhh my mistake! I was wondering why everyone was querying it...I missed out a vital bit that I had thought in my head and didn't actually write!
I had meant to say, if it's hard to visualise eating more veg than you currently do and you want to increase it, but gently, just double up on the ones you do routinely eat, or work up to triple, and when you've incorporated that amount into your diet, introduce a 2nd or 3rd one to make up 1 serving of each. That's what I did as I changed my eating habits, appetite and the way I constructed my meals.
So in the case of 2 x peas you could add in something that goes nicely, for example you could make braised lettuce and peas (really good over rice with leftover chicken) or you could do peas and broccoli with your fish, or whatever.
A fresh grated carrot salad, just add in parsnip or celeriac or beetroot. It's not more in volume than you were already used to but you've now got 2 different veg instead of the 1. Or 3!
I like a warm salad and basically just throw anything in there that goes together well. Roast it all up and job done. Beetroot, squash, tomatoes, courgette, peppers, red onion, are staples.
Similarly I make a fresh salad with pretty much anything I can find in the fridge - the more variety there is the more you'll find that random things actually go very well together.
If I have either of those for dinner it can easily be 4 - 6 (true, official) servings plus extras like aromatics, herbs, nuts and seeds.
And of course chunky soups are great too.
I guess it helps a lot that I've always liked most veg. It's obviously going to be much harder if you're not actually keen on them and are just trying to eat them for your health's sake.
