While both the agricultural production of fruits, vegetables, and meat produce carbon emissions, agricultural plants produce far less than meat production does. Limiting the amount of meat one consumes similarly reduces the amount of carbon emissions a person creates, as the majority of their food is comprised of less carbon emissions. Doing even tiny daily tasks or goals to minimize emissions can help to prevent the further acceleration of climate change as well as global warming, as farm animals, especially cattle, produce a rather immense amount of methane.
So far this week (including the weekend) I've had spring onion, baby corn, broccoli, carrots, lettuce, apples, raspberries, cantaloupe, honey dew(I think that's what the green melon is called), pineapple, tomatoes, jalapenos, lime, lemon, and oranges. I think my usual favorite would be either pineapple or raspberries, but the salsa I had over the weekend was really good. So I guess if I'm going off of the main ingredient, then tomatoes.
