It might be helpful to just sit down and make a theoretical menu for the week. i'm not great at doing this on a regular basis, but we have 2 deep freezers in our basement so i never have to worry about meat and i always keep lots of frozen veggies on hand so we can always have a veggie even if nothing fresh at the store looks good.
it's helpful to think in terms of meals vs. individual items, then make sure you have what you need for cooking them.
so quick and easy breakfasts for us would include yogurt with granola, fried eggs on a toasted bagel, scrambled eggs with cheese, oatmeal, zucchini bread, banana bread (the breads having been made the day before), kefir-based smoothies with fresh or frozen fruit and juice.
quick lunches might include: nut butter/jelly sandwiches, soup, salad, egg salad sandwiches, tuna salad sandwiches, grilled cheese sandwiches, annie's mac and cheese.
in your situation i'd be inclined to make a big batch of pasta sauce ahead of time so all i had to do was boil some noodles and throw together a salad for a couple of dinners. also maybe a bit batch of chili or soup so it could just be quickly heated up and either eaten alone or with some crackers or bread or salad. i always keep some containers of organic fire roasted pepper and tomato soup from Costco in the cupboard, so if i'm in need of something super quick and easy for dinner it might be that soup and grilled cheese sandwiches.
and you might be feeling cooped up and have the desire to get out of the house, so if budget permits, you might plan on taking the LO out to eat someplace for dinner one night for a change of scenery.
