BLT's with Avocado and Pesto Mayonnaise

BLT's with a fresh twist, avocado and pesto mayonnaise.  Summertime's favorite sandwich!

BLT's with Avocado and Pesto Mayonnaise

Let's just call this a BLAT  ~ bacon, lettuce, avocado and tomato.  And let's up the game on the mayo a bit and add some pesto.  There you go, the best BLT you'll have all summer.  Yes, summer, the only time to make BLT's are when tomatoes are in season.  And are they ever in season right now.  I'm obsessed with them all ~ every kind of tomato I can find and try at the farm.

Ingredients for BLT's

You want to see some tomato pics?  Here, take a look.  I can't help myself, they are gorgeous.  And the taste, oh man, just bursting with sweet, fresh, real tomato flavor.  We're eating these guys every day.

Sliced heirloom tomatoes for BLT's

I love a good BLT, and by that I mean simple and classic ingredients.  White toast, thick-sliced bacon, crisp lettuce, the star ~ tomatoes ~ and a generous slathering of mayo, that's the ideal.  But I also love avocados and pesto, also abundant this time of year.  So I decided to put it all together and the BLAT was born in my house.  How do you like your BLT's?

We just had these again last night and I hear August, 20 is National Bacon Lovers Day, so I think we'll have them again.  Did you know they say bacon cures hangovers?  Just sayin' ~ I'll let you know if it works.  Cheers, Kelly

I love a good ol' BLT! Especially with homegrown tomatoes. And the avocado and pesto mayonnaise takes it up a notch or two. Well done!
