During the summer, we barbecue a couple of times a week. I have the classic Weber charcoal grill. I grill beef and chicken directly over the coals, but I’ve been using these grill mats to cook vegetables and fish. They are so thin that they look like they would incinerate in a second, but they are impervious to high heat. They are easy to clean, too. Nothing sticks to them. — MF

Amazon Fresh is Amazon’s grocery shopping and delivery service. They sell everything a large supermarket sells, often at better prices. You can sometimes get same day delivery, but it usually takes 24 hours. This is a huge time saver for our family. You must be an Amazon prime member. — MF

Buying in bulk does save, but when we buy the large plastic container of mixed greens from Costco, it usually gets slimy after 4-5 days. I tried the paper towel hack and placed one sheet in the middle and one on top and it extended its shelf-life by one week! — CD
