Good for you! These shifts are tough at first but you get used to it. I do mostly veggie heavy meals but usually add some protein so people aren't looking to eat again in an hour.
Made this yesterday for a chicken base but you can just skip if and do the rest without any protein, I have beeter luck reducing protein than cutting it.
I am partial to Trader Joes stuff I really like the Trader Joes Soyaki sauce, which I use very sparingly for myself but other family members use more. Typically I marinate a big tray of chicken thighs for a little while and use it as protein in all sorts of mostly veggie dishes. Marinate about 2 hours then either bake or grill, everyone loves it and it is a great go to or starting point, to me it takes up a little flavor bot not enough to be an issue if it isn't the main part of the dish.
While the chicken was baking
Frozen cauliflower rice, saute' at high heat, and put aside.
Saute' Stir fry veggies in another pan, I like TJ fresh but frozen any kind also work.
I pull out my veggie portion and heat about 1/4 cup of the Soyaki sauce with their veggies, anything you like is fine though and making your own is fairly easy.
Zoodles with pesto alone or with a bit of chicken or shrimp.
Have ice water in a bowl ready in the sink & a big towel.
Boil the zoodles 3 min, empty into a colander then drop into the ice water until it is chilled to stop them from cooking.
strain again then drop onto a big towel to twist out the extra water. You can put this aside a few hours if you need to do other things.
Make a pesto with fresh basil, some parmesan, pine nuts and olive oil, this is no cook and can be frozen.
Just saute' the zoodles in some oil, toss in the pesto and add whatever protein you would like or none.
I adore eggplant Parm or Rollatini, little pizzas can also be made with eggplant.
Avocado toast
TJs makes Jicma taco shells in the fresh veggie areas and we love that for taco, beef shrimp or fish with a little sour cream blended with siracha and lime, I serve heavy on the veggies with a smidge of other stuff but they can be only veggie too.
From google just to see what they look like
TJs also makes cauliflower puff rounds that I really like with a burger, but I guess a portobello burger too.
Portobello, oven to 400, pull off stem and I use in a omelette another day. Sprinkle inside with some parmesan cheese, then sprinkle small bit of breadcrumb (or just use the cheese) them a splash of olive oil and bake about 20-30 min - great alone or as a portobello burger
From google
Wegmans soy noodles are really great in chicken soup, they just need to be rinsed a few times to get rid of the strongish smell, my chicken soup has A LOT of carrots and celery, I mean a lot, the chicken is a small bit.
