Prometheans must, essentially, spend Prosperity to continue expanding. Therefor, they need ways to increase Prosperity.
Some ideas:
Stimulate Growth: Tax reduction modifier on province. Idea being that reduced taxes improves the lives of the commoners, allowing for them to support more children and generally be healthier. Probably also the bread half of Bread & Circuses.
Sponsor Local Festival: Costs some money, applies timer type modifier to prevent spamming.
Open For Settlement: open settlement of province to the realm or even foreigners. Not even close to as effective as the Settlement decisions but still produces a small amount of prosperity every once in a while. Events depicting friction between locals and settlers could make things more interesting. Some events just for flavor, but most would make you decide between two potentially unpleasant outcomes. Lose some prosperity, or deal with increased revolt risk? etc.
Infrastructure Projects: Invest in local infrastructure like roads, bridges, irrigation systems, dams, etc. These could be long-term temporary modifiers that trigger periodic events to increase prosperity. I'm not sure how many of these should be possible to have at once or what determines which shows up.
