I'm getting tired of this notion that breakfast food has to be some specific sort of thing. It doesn't. It can be leftovers from the previous day's lunch or dinner, remixed into something different.
This morning, I made 5 whole wheat roti, and reheated some daal and subzi from Monday night's dinner. It was quite filling and delicious.
Please don't let the big corporations dictate what you eat and when you eat it. If you have a hankering for oatmeal in the afternoon, go for it. If pasta in the morning sounds good, eat it! And in all seriousness, any time is a good time for adai or dosa.
The roti was 2/3 cup whole wheat flour, 1/3 cup all purpose flour, just about 1/2 cup~ish of water that I kneaded for a couple of minutes, rolled out, and cooked on my dosa pan.
