I have a peanut butter sandwich on whole wheat and an apple for lunch most days, but our dinners are usually pretty substantial with a meat/chicken or fish, rice or potatoes, vegetables. My vegan son just has a veggie burger instead of the meat.
"Not hungry" are words I don't think I've ever heard in this house. On the rare occasions when I'm fixing dinner for just myself and not the two men I usually make a huge salad and top it with a can of salmon and lashings of Ranch dressing. I do that when the men are having pizza. I'm the one person in the world who doesn't like it.
Soup and a grilled cheese sandwich is good, too.
I think Murrmurr's homemade egg McMuffin sounds great. We may have that tonight. I had to go to Walmart for something and lately that place just exhausts me.
