I read that. But I don't think it has to be a full portion. If you squeezed lemon juice and grated zest over your broccoli or added a spoonful of flaked alonds or seeds to porridge, that would count
For fruit most weeks I have:
apple
pear
banana
melon
grapes
frozen blueberries
orange or clementine
then also one or two of these each week depending on season: strawberries, raspberries, rhubarb, dried apricots, grapefruit, peach, nectarine
Veg weekly:
onions - red, white, spring
garlic
peppers
courgettes
aubergine
peas
carrots
broccoli
tomatoes (I know they're not strictly veg but in veg meals)
potatoes with skins on
lettuce
mixed salad leaves (rocket, watercress etc)
cucumber
avocado
Then a few of these: fennel, asparagus, spinach, cabbage, kale, chard, sweet potato, butternut squash, mushrooms, leeks, olives, kidney beans, butter beans, edamame, broad beans, swede, sweetcorn, celery
Add herbs, nuts, seeds - fresh basil, cashews and parsley in home made pesto, mint or dill on sauces and stirred into rice or couscous. Add garnish of sesame, sunflower, pumpkin seeds
I vary between white, brown, red rice, wholewheat couscous, barley, potatoes for the carbs - afaik they all count towards the 30 variety too
