If you didn't feel bloated and gassy, then it was a combination that was able to be handled by your digestive capacity.
There is more nuance to food combining than the broad statements that are generally made like eat fruit alone. But I'm general, of you feel good after you finished eating, it was a good combination :-)
Tomatoes are technically fruit. Here they are very ripe, fresh and sweet. The addition of vinegar (salad dressing) aids in digestion. Everything about this meal looks fresh, balanced, tasty and nutritious.
High five!!
