The philanthropist and entrepreneur joined "TMZ Live" Tuesday to talk more about her Bstrong initiative, which is raising millions and sending aid to the war-torn country. Bethenny had announced her partnership with Global Empowerment Mission, pledging $10 mil in food, medical aid and other supplies.

All of that aid's being boxed up in her South Florida warehouse ... but on top of that, Bstrong continues to raise even more cash -- more than $5 million -- to help fleeing Ukrainians at the Poland border relocate. As for how she's pulling off this extraordinary humanitarian effort -- Bethenny tells us it's all about being "efficient and lean," and knowing where help is most needed.

She adds, for anyone looking to donate their cash to her initiative, your money certainly won't go to waste 'cause her team is on the ground working.

It's no surprise Bethenny's among those leading the charge ... she says she's gotten lots of training in relief efforts for natural disasters, like tropical storms in Texas, the Caribbean and the Australian wildfires. She says her history of putting on big productions, with many moving parts, has helped hone her get-it-done mindset.
