I love that portable love pizza, too- a halved bell pepper also works well.

I live in a major city, but let me try to post a few ideas for things I think you can find easily, or would be worth ordering (like flax meal or coconut flour. I buy the brand Bob's for both):

Breakfasts:
There are countless ways to do eggs- try something new like shakshuka (an Israeli dish where eggs are poached in tomato sauce) or sunny side eggs with radish hash browns (even if you think you dislike radishes, try these!)
On days where you have carbs to spare- Greek yogurt with all natural peanut or almond butter
Leftovers!
You can make a hot cereal from flax meal or coconut flour- check out recipe forums or google low carb hot cereal

Lunches or dinners:
Salads are obvious but you can also try lettuce wraps with say egg salad or grilled veggies and baba gnoiush, lettuce tacos, a salad with sautéed spinach for a base for a hot salad, etc.....

Those zoodles as mentioned! Making an Asian peanut sauce with tofu is a favorite for me.

You can make great Thai curries with coconut milk, or soups!

I love making bread with this recipe-

A current favorite is to make it for avocado toast- sometimes I add an egg, sprouts and roasted veggies, goat cheese, etc.....
It is also good for an open face cheese and tomato melt
Pb and sf jam

I love making a quiche to cut grocery bills for dinner- check out e pizza quiche in recipe forum. It is easily adapted to be veg
I usually serve it with a side salad

Since you liked the portobello pizza, you might like making an eggplant parm. You can "bread" it with flax or Parmesan (the kind from a can), but I usually just leave it "naked." I layer the eggplant, sauce and cheese- and add Parmesan/parsley after it is done.

I often like a grazing plate- I make/ buy crackers made with flaxseed (recipe forum) but others use melted cheese, too. I pick a dip or two- guacamole, hummus, tzatiki, baba gnoiush, herb/ranch......and then I cut a veg veggies, and sometimes a pickled veg, too. Then I cut up about 2 oz cheese, and I'm set. Artichoke hearts, olives, marinated mushrooms all fit well, too.

I also love snacks- veggies with dips, nuts and seeds, cheeses, kale chips, seaweed snacks, etc....coconut milk makes a great ice cream.

You might find you don't need to be quite as strict as 25 g carbs. As a veg, you are already drastically changing the really nasty stuff (grains, sugar, etc...).
You will figure it out as you go along. I think a lot of veggies would've better off at a slightly higher carb intake, but eating less processed foods.
I tried to be super low carb (under 20-25) for years but ate way too many boca burgers and tofurkey slices.
Eating more veggies did bump up my carbs, but it was a much better diet!
30-35 is my magic number, but like I said, we are all different.
Still- I can't believe anyone is better off eating just 10 less carbs a day, but most are coming from hilghly processed foods. I also, think it is important to choose foods from a variety of sources (I.e. It is bad to overeat any food whether it is soy, dairy or anything else). Getting a variety ensures you get a better variety of nutrients.
