I want to say pasta because I love me some pasta but the Asian in me will be disappointed if I don’t go team rice I honestly love all three though. I eat rice the most and bread the least.
This is tough, but I'll say pasta. There are so many yummy types of pasta. Bread is a close second though, and rice is good, but I can't pick it over the other two.
I voted bread simply for sandwiches. I eat them more often than not and the bread can make or break a sandwich! But I do make rice and pasta often as well with bigger meals. My two main ones are jasmine rice and couscous.
I LOVE pasta so I have voted for that. But if there was one I really don't think I could do without, it would be bread, just because of how versatile it is.
