There are good sauces you can make from canned tomatoes in 20 minutes (depending on your prep speed).
My go tos are Putanesca & Vodka sauce, but there's a lot more you can do. Mark Bittman's How to Cook Everything has a simple recipe and then a big list of variants, most of which can be done in 20 minutes.
It may depend quite a bit on the pill. As an adult I can easily dry swallow things like ibuprofen. But I'm not sure about something like oral steroids.
I was prescribed them as a kid due to a particularly bad poison ivy reaction. I couldn't swallow pills at the time, so after running through all the tricks to teach someone, we ended up grinding them up and sticking them in ice cream. It was something like 15 years before I could eat cookies and cream again without tasting steroids. Grinding them definitely exacerbated the problem, but I'm not sure how I'd fare if prescribed the same pills again.
