SQL Server 2012 :: Dynamic String Replacement

I have a table with the following data;

CREATE TABLE #Tab (Data Varchar(100))

INSERT INTO #Tab (Data)
Select 'Apple=5,Orange=10,Banana=11' UNION ALL
Select 'Apple=10,Orange=1033,Banana=0' UNION ALL
Select 'Apple = 120,Orange = 1,Banana = 112'
Select * from #Tab

How do I replace every value before the '=' but leave the comma.

Here is what the final output should look like

CREATE TABLE #TabFinal (Data Varchar(100))

INSERT INTO #TabFinal (Data)
Select 'Apple,Orange,Banana' UNION ALL
Select 'Apple,Orange,Banana' UNION ALL
Select 'Apple,Orange,Banana'

Select * from #TabFinal
