Are people purposefully planting onion grass? I'm not in Cali... and granted some of my neighbors look like they've intentionally planted it all over their yard.... but I'm fairly certain it's not intentional.
I feel your pain. You're describing my dogs to a tee. I can understand how it could be confusing to people who have never had to deal with this. What breed is your pupper if you don't mind me asking?
Can't speak for the other user, but we have had three West Highland Terriers/Westies. All three of them did this at times and could be super picky at times to the point of making them sick.
They have really strong internal clocks, and if their schedule gets out of whack, or if we're slightly late, or if something gets their appetite moving earlier than normal, this happens.
Their stomachs start producing acid whenever they think it's time for food, and if they don't get it in time, they throw up stomach acid.
We have it decently under control these days due to years of experience... but it takes 4 meal times and a small snack before bed. One or the other of our current two will still get sick once every few weeks.
I have actually had to dial back their portions carefully the past few weeks because they were both a bit overweight. So I can confirm that this can be a problem even when they are getting enough food.
Cheesy Gordita Crunch is the correct answer, but probably best to also try basic items just for comparison.
I remember the dark days when the Cheesy Gordita Crunch was a limited time offer and it kept going away and coming back. I would always go A LOT when it showed back up. So glad it seems to be a stable staple now.
Oh! And fwiw - they actually sell the Fiesta sauce in some grocery stores now... that is one of the key ingredients that makes it so good. That sauce goes well on/in so many things.
I enjoyed uprising. It deserved a sequel too though, and was clearly leading to things it didn't get to wrap up sadly. Well worth watching anyway though.
