For me, personally, I think I could adjust to a vegetarian diet, I do enjoy a wide variety of fruits, vegetables and grains, but my partner, he has a much more, lets say, limited palate when it comes to fruits and vegetables. Do you eat a lot of beans and nuts or like, what are your main food staples?
I think I've eaten tofu before, but I can't really remember, I don't think it left a strong impression on me. I can tell you right now though, my partner would not touch tofu with a ten foot pole, and to be perfectly honest, I don't really know why. I think he is a super-taster or something, but he is extremely picky, anything which is bitter or sour, or has a strange, unusual, or even slightly different texture elicits a, "hmm... yech.. nibble nibble what is this!?" and that's if I can even get him to try it in the first place. We mostly cook at home, but have a pretty limited diet of pasta, rice, potatoes, eggs, lots of dairy and cheese, broccoli, tomatoes, onions, corn occasionally, and chicken or pork, with some limited red meat, and fruits being mostly apples, strawberries, watermelons, plums or oranges depending on the season. I'll eat a much wider variety of veggies, but he won't touch any kind of beans or nuts.
