The first four sound like an easy quick meal: veggie saute with carrots and mushrooms, onions for better flavor, and whatever else is tasty and on hand (celery, bell peppers, tomatoes are a few promising options) served with drained canned beans (thrown in the pan to warm or served cold/room temperature in summer) seasoned with garlic, herbs, and cayenne powder or chili flakes. I could happily eat that several times a week and unlike many "health/diet" meal suggestions it's both affordable and filling.
