We have some other threads here that share lunch and sandwich ideas:
And here are 50 vegan sandwich recipes:
Some of my current favorite sandwiches:
mash some canned chickpeas in a bowl. Add some chopped onion and celery. Add a dollup of vegan mayonnaise (some brands are Just Mayo, Vegannaise, Spectrum Eggless Mayo, Earth Balance Mindful Mayo). Mix it all together and add some black pepper if you like that. Add this spread to a few sandwiches and you are good to go.
Another is to spread some canned tomato paste over your slices of bread. Add some olives, onion, cooked green pepper and mushroom for a pizza sandwich.
Thinly sliced tempeh, cooked savoy cabbage, sauerkruat sandwich
Sliced tempeh, sliced tomato, vegan mayo sandwich
Tortilla wrap with hummus, sprouts, red pepper, cucumber
Whole wheat pita with can of fat free refried beans (the full fat ones often have lard in them but the fat free ones are usually vegan), salsa, tomato, green pepper
If you make soup ahead and bring a thermos, you can have hot soup that way. I do this often. I make a huge batch of soup (sometimes in my crockpot) and store it in a large container in the refrigerator. Each morning during the work week, I will heat a portion in the microwave, add it to my thermos, and bring it to work. It stays warm all day. I will have a homemade slice of bread or a muffin with it, or bring along a salad too.
I always pack my lunches and bring them, and almost always eat them cold simply because I work in a building with over 300 people and we have four microwaves, so there is always a line for those. I just eat my food cold because I only have a half hour for lunch lol. I've done it with soba noodles and bok choy/sesame seeds, or with beans, veggies and rice, or black beans and kale and sweet potato curries etc.
However, there is a coffee machine in the cafeteria that also has a hot water spout and I utilize that. I'll bring some oats in a baggie with nuts, raisins, spices, stevia. I simply pour it into a bowl I bring, and add some hot water from the coffee machine to it for hot oats. This works for couscous also.
Or I will make a quick smoothie in the morning and bring that to work, though I usualy drink it as a post workout snack when I first get to work after the gym.
