It can really be as simple as:
1. A knee dominant exercise (squat variation)
2. A hip dominant exercise (deadlift variation)
3. A horizontal push (you can do your bench presses here)
4. A horizontal pull (some type of row variation)
5. A vertical push (for instance your shoulder presses)
6. A vertical pull (your chinups, lat pulldowns, etc)

You can stick to the same exercises M-W-F or pick two different sets of exercises and alternate them in an A and B format. You could throw in some core work either after your warmup, before your cooldown, or even during rest periods between sets. If you still want to cut time, divide the six exercises into 3 supersets. This is not really saying this is exactly what you should do, but this is to show that you can hit full body with the same amount of time. You were doing 6 movements in a split fashion and you are still hitting six movements. This way, you are also training movements more frequently which for a beginner is important from a neural aspect.

Again, not saying that you should do full body, although I do personally favor them for myself and favor them for beginners as well. The choice between FBWO and splits is something that you have to decide based on your goals and enjoyment (don't overlook the enjoyment factor). However, if you are dismissing total body workouts because of time, I think you need to reconsider that aspect.
