Have you checked out the DC vegan restaurant options? Fruitive has great fast casual offerings, and Beefsteak, though not completely vegan, has a slew of vegan items on its menu!
Really? I mostly eat at home because I love cooking, but it might be nice to get out more too. 
In a city like DC, there's lots to explore in terms of the restaurant scene. Whole Foods has opened yet another location in DC, so you've got access to great produce! 
I am pretty loyal to Trader Joe's. My best friend, he's vegan and the one whose trying to get me to cut out all animal products, he's shown me a bunch of great vegan products they have there. 
What's the best recipe you've prepared so far? Ethiopian cuisine is great for vegans, so you might want to look up some recipes!
My favorite vegan recipe is these rockin black bean and sweet potato tacos. So healthy, a ton of protein, and they are delicious. 
It sounds like you're into Mexican food. You can make vegan fajitas if you have a sheet pan. Street Corn Salad is another easy and tasty option.
Oh, I love street corn salad. This conversation is making me hungry, haha. I am trying to find some good vegan options for summer parties right now. Fourth of July is coming up. 
You're in luck, as there are a ton of appropriate recipes! Lentil Burgers are a great way to go, as are Vegan Sloppy Joes and Sriracha Coleslaw! It's amazing how many vegan solutions are out there these days.
Those sound really good. Some of the recipes I've seen....carrot hot dogs? No thank you. I did see this one thing, it was a vegan potato salad made with bean mayo, I might try to make that this weekend as a test run.
