To the vegan Jellies: Is it difficult to reach 2000 calories a day?

I’m not a vegan and I don’t know what it’s like to be vegan. I was thinking about transitioning, though. I want to make sure I get enough calories since I have a fear that I may not be getting enough. I’m pretty thin already and am looking to gain muscle. Can someone break down what a normal nutrient day would be for you or what it could be for me? Fats, carbs, protein, etc. Thank you for sharing your experience.
