With the no beef/pork/salmon, the 6 o'clock scramble might be tough for you. But it's been a while since I checked it out.
Here are some of my vegetarian favorites:
veggie tacos: Saute onions in a pan. Add in broccoli, green pepper & mushrooms and cook a few minutes. Then add in one can each of zesty tomatoes (w mild green chiles), black beans and pinto beans. Cook about 5 min or until veggies soften and beans are heated through. Serve on soft tacos with sour cream & salsa.
chickpeas with feta & spinach:

mushroom stroganoff: this is a vegan recipe, but I use regular dairy products and it is delicious

What about a veggie lasagna? Make one on Sunday and have the leftovers on Tuesday or so. Use the no bake noodles so the only thing you're cooking is the lasagna itself.
We also have black beans & brown rice on hand at all times for a quick meal in case a day gets out of hand and whatever I've planned can't get prepped.
Have you ever done a crockpot chicken? Big hit with my meat eaters. Skin a chicken, season it and add a quartered onion and a few crushed cloves of garlic. Turn it breast side up and cook for 5-8 hours on low. (Fryers for 5, larger roasters for longer.) Pull apart and serve with salad and a veggie.
