What's your favorite fruit or other interesting ingredient to use in smoothies?

[Mabouya]

For the last year of so I've been working out at the gym after work (the gym's at work so it's convenient and free) and immediately afterwards I have a Clif Builder's bar, take a shower, then I go back to my office where I have a smoothie for "supper." Most of the time it consists of water, a meal-replacement powder, ground flax seed, a banana and some frozen strawberries.

It's occurred to me that I should probably have a bit more variety in the fruit add-ins. For example, blueberries could be a good substitute for the strawberries, but I'm wondering if anyone out there uses anything really new / interesting / healthy that would also work.

TIA

I am a big fan of adding some frozen pineapple and/or mango and sometimes papaya. Pineapple and mango have a lot of C and other stuff that I always figure are good to have. My supermarket doesn’t always have these frozen but Costco always seems to have them. Just be careful of going too heavy with pineapple and mango due to sugar. I use about 100 grams or so.

And I agree with your thinking on berries. There are some premixed frozen I have found that are blueberry, raspberry, blackberry, strawberry that are nice.

Given where I live, mangoes are the most popular smoothie addition. Along with a little honey it's tasty combo.

Dark sweet cherries and peaches/nectarines for me.

Blueberry/strawberry combo is my go-to but mango is really nice too. We get a CSA box that often produces more fruit than we can reasonably eat so a lot of that goes in, too - peaches, nectarines, and other stonefruits.

Oh hell yeah! Our tiny tree gives so many mangos. We freeze them and we have nearly year-round mango.

We have the only thing better than a mango tree. A dozen friends with mango trees. They just seem to show up all the time along with avocados.

Even if using fresh fruit it is good to freeze them solid prior to blending.
Bananas can be sliced and frozen flat in ziploc bags to make portions.
Getting that cold milkshake consistency makes smoothies especially delicious.
