Hi, at this age your solids are really just for "practice" and getting used to eating textured things and milk really should provide the vast majority of your LO's nutrition. So, I definitely wouldn't do a meal before your first milk feed right now as it might cause him to take less of his bottle. If you're comfortable with your routine the way it is, there isn't really a need to change it right now. If you want to add a meal, I would add dinner sometime between your last two milk feeds (not including the dream feed). You can do similar foods, or do rice or some other sort of cereal or something like that (you can mix it with formula and then not worry about losing those nutrients).
Good luck, I found introducing solids to be one of the more confusing things to do. Tracy gives some great advice in Baby Whisperer Solves All Your Problems in the solid food chapter as well if you're looking for a reference.
