Calling all Vegetarians and Vegans!!

Curiouscreaturee covered a lot of the breakfast bases! If you're looking for more protein and don't mind fake-meat products, I really enjoy most of the vegetarian sausage out there. English muffin breakfast sandwiches are nice if you want something more savory than most other egg-free breakfast options. The sausage might be a problem if you can't have soy, but I'm sure soy-free options are out there.

As for snacks, carrots are good if you don't mind something noisy. If you like them, seaweed snacks are great (but can be a little messy at least for me). Healthy popcorn flavors are another convenient snack that I recently discovered I liked. If you can find one with just olive oil and salt, maybe some herbs or something, that's my favorite variety. As for protein again, other than nuts an options might be roasted chickpeas? If you like chickpeas, that is really easy to make and delicious. You can find some good recipes for it online.

steel cut oats w/ blueberries or raspberries

I usually just eat some fruit on the bus to work. If I've got time I'll eat oatmeal with berries or greek yoghurt with honey and nuts.

For more protein try quinoa

Dinnertime favorite is sauteeing a bit of onion and garlic on a pan, then adding cumin, curry powder, and chili powder. Then after those things have mingled for a bit I add chickpeas and crushed tomato. Serve over a bed of rice & add a side salad.

I really like peanut butter (not too much ) and apple wraps.

i like to mix greek yogurt, fruit, and oatmeal and let it sit overnight and have it for breakfast. it's so delicious. My go-to was oats, vanilla yogurt, blueberries, and PB2.
Someone already mentioned quorn products, but they're super tastey and have a good amount of protein. Their chik'n cutlets are my favorite because they're so low cal and they are so easy to put in different recipes that call for chicken.
I also really like Texturized Vegetable Protein- high in protein and low in calories!
I LOVE lentils. I make a lot of lentil tacos. They're also pretty high in protein and I think they taste better than quinoa.
As for snack, I snack on protein bars. My favorite are pure protein. 20 grams in a bar!
I think my diary is open, and I aim for 120-130 grams of protein a day if you want to check it out. Granted, some of it comes from eggs, but still, feel free!

Good luck!

edit: typo

pescatarian here, not sure of the vegan limits, but my every day breakfast is oatmeal with peanut butter, dried cranberries, chia seeds and five semi sweet chocolate chips

I like plain greek yogurt with a bit of honey and maybe some fruit added. I also made a very tasty, very filling soup today made of black-eyed peas, frozen baby lima beans, frozen butternut squash, and white wine broth (from a box, but not bad nonetheless, but you could use plain tomato juice, i squeeze my own and use as a soup base). I make a lot of soups with beans and tofu. Full disclosure, I'm not a vegan or vegetarian, but i don't eat much meat.

Thug kitchen is great too, i agree with previous posters!
