are you suppose to eat this warm or cold?
I prefer them cold, but I suppose you could eat them warm.
These looks wonderful! Perfect for a nice light and quick lunch.
Thank you so much, Christine 🙂
#5. Tuna the tomatoe halves over, don’t you mean “Turn?” LOL 🤔
I will be making these real soon, Thanks.
Hi Lisa, auto-correct got me and my bad eyes again, lol 🙂 Thanks for letting me know.
why just use the bottoms – what about the top half of the tomato?
You can use the top half if the tomato is big enough to make two.
I love anything to do with tomatoes
I love tomatoes too, Ike 🙂
