Meatless Monday–Gooey Guacamole Grilled Cheese

To be honest, this sandwich was a way to use up some groceries before they went to waste.  I had grilled cheese sandwiches planned so I could use some fantastic cheddar I’d found.  But then I had an onion, some fresh salsa, and one lonely avocado just clinging to its last day of goodness.  What the heck, I thought–Why not mash up the avocado, add the last bit of salsa to it, and put it on the grilled cheese with some onion slices?  

Now the question is “Why not do it again?”  Because man, was it good.  Gooey, and melty, and good.  I can’t wait to repeat this sandwich with some spicy pepper jack.

Gooey Guacamole Grilled Cheese

an “Apple a Day” original


1 small avocado

1/4 c. your favorite salsa or pico de gallo

4 slices your favorite bread

2 TBSP butter or mayonnaise

4 slices cheese (cheddar, Monterey Jack, or Pepper Jack recommended)

sliced onions, to taste


1.  Preheat a griddle or large skillet over medium-low heat.

2.  Mash avocado and combine with salsa or pico de gallo.  Add salt or pepper, as necessary, keeping in mind that the cheese will add saltiness.

3.  Spread butter or mayo on on side of each piece of bread.  Assemble sandwiches so guacamole and onions slices are in the middle of the cheese slices.

4.  Cook sandwiches until cheese begins to melt.  Flip and repeat until bread is nicely browned and all cheese is melted and oozing.  Serves 2–have the napkins ready!

    Lucky! My husband basically hates all foods. He would never eat this. I, on the other hand, will quickly devour it. It looks fabulous!!!

    This is perfect for using up a small amount of avocado.

    Yay for men who eat everything! I've even managed to get Jon to eat vegan a few times! (Not that I would ever make him do that full time – I don't even make me do it full time!) But this? I wouldn't have any trouble getting him to devour one of these! Yum 🙂

    I love throwing random things into a grilled cheese. My recent favorite has been leftover roasted broccoli with cheddar! We love all things avocado too so I'm going to have to remember this one.

    As a recent guac convert, I'm pretty pumped about this idea. So glad you shared it!
