I found some simple things helped increase my numbers.
Instead of having a single fruit with the waffles I make, we have a fruit mix,
the waffle batter also has wheat, cornmeal and oats, which make a crisper waffle, and it's 3 different plant foods.
We have bean burrito's for breakfast, so instead of having the same all week, now I have half one half another. Or any recipe that calls for multiples of the same thing, like when I made refried beans, I used 3 different beans instead of all blackbeans.
I also batch cook and freeze my own all-veg sauce. I leave it pretty plain, so it can be pasta sauce if you add more herbs, or add paprika etc to make a sauce for roast veg and cous cous etc. I puree them all smooth, always tomatoes, but then I've added various things, celery, courgette, carrot, butternut, spinach, beetroot, onions, garlic, lettuce, corn, the reduced boxes of veg you can get in Lidl are ideal.
