I'm not vegan but my dinner today fits the bill, as long as you use canned chickpeas:
- cut kabocha [pumpkin? squash?] into large chunks
- boil it in water or veg broth, alongside some seasoning
- puree it, send it back to the same pot
- [optional] add tomato paste
- add chickpeas, let them simmer together until the broth thickens due to the chickpeas juice
Amounts are eyeballed (in your case, heart-measured). Seasoning is up to your tastes, but if unsure: I use salt, curry powder, cayenne pepper. It tastes really great with some bread.
And yes, it freezes really well.
