I made what I called "Rainbow Salsa" a week ago.
I had everything on hand to make salsa and we were going out of town so I wanted to use up all those veggies that would have gone bad.
I had Green, Red, Orange & Yellow Peppers
I had Yellow Tomatoes (and one Red)
I had Purple Onion
I just use my food processor to blend it up chunky.
p.s. Yellow Tomatoes taste exactly like red ones.
But I hear they are more expensive. I had not bought these, they were given to me.
