Food ideas - meat free, low carb, nut free

Eggs and dairy. Lots of vegetables. Chia seeds. Hemp seeds.

Amy's Kitchen products (many) are even kosher certified... frozen dinners and some come with less salt options and you can also choose nut free in their search engine... They have symbols by the ones that are kosher and nut free . Also, their canned items are non-BPA lined.

Is there an option of buying lunch there? you could buy meat and bring veggies with you

or you could eat a big meal before work, then get a smaller snack (eggs, cheese, seeds (pumpkin, sunflower)) during work and eat a bigger meal once you get home?

Salad with any of: fish, cottage cheese, hummus + veg, baba ganoush + veg, marinated & pan fried tofu.

Are you allowed to bring kosher meats, or nothing at all? If you are allowed to bring kosher meats, you could get a kosher chicken and roast it, then use the bones to make soup after. Roast chicken goes a long way for lunch and you can also have chicken & veg soup some days as well.

Another option is roasted veg soup. Just roast the vegetables you like in the oven with some oil and a spash of vinegar and rosemary and salt and pepper. Then blend it all up into soup. You can vary the glycemic load by including more or less potatoes or beans in there. Super yum with a little sun dried tomato pesto on top.

Bean soup is another good one. Basically saute some garlic, onion, carrots, celery. Add vegetable broth, then add different kinds of beans (from a can or pre-soaked & cooked / or pressure cooked), cook, add a can of crushed tomatoes and a little lemon juice if you like, cook some more. Blend half of it and add it back in. Season to taste. (I don't have the proportions here, but you can go with what makes sense to you) You would have to look into if this has too heavy a GI for you, and adjust the bean to veg proportions accordingly.

Veggie burgers made from beans and veggies are always good - many 'from scratch' recipes.

Homemade falafel can be made SUPER cheap - dried chickpeas, salt, onion, and parsley is all you need. Some add a starch or flour, but it can be done without (I am low carb for medical reasons, too, so that's what I do).

Homemade hummus is also easy to make, and in some areas they make it with olive oil rather than olive oil plus expensive tahini, so I make mine with chickpeas, lemon juice, salt, and olive oil (some add roasted or raw garlic, too).

I've seen some neat veggie-only sushi-like recipes - some nice veggies (carrots, cucumber) combine with a little avocado, wrapped in seaweed, and then some soy sauce to dip it in.

Chili, of course.

A super cheap but very filling soup is to take 1 eggplant, 1 onion, and roast in oven, with skin still on, until soft. Peel, blend in a blender, and add to 2 cups veggie broth. Heat until fragrant, then just add salt and a little lemon juice to taste, and that's it. Very rich tasting, nice.

If you can do beans all right (not too many carbs), you could look at socca bread recipes (tons online) - it's a traditional french flat bread that requires chickpeas, oil, water, and salt - that's it. It's officially made with chickpea flour, but in Europe, where it's not as finely ground as in the USA. I just bought dried chickpeas and ground them up a little at a time in the blender. I've made this as a base for a pizza and it works quite well, or with herbs added it's a nice breadish side dish.
