Tips
Every microwave has different power levels, so check bacon crispiness after 4 minutes and adjust timing as needed for your appliance.
Medium toast prevents the bread from being too rough on your mouth while still providing structure for the sandwich.
Compress the finished sandwich with your palm to mimic deli-style wrapping and ensure all ingredients stay in place.
Good to Know
Best enjoyed immediately. Can refrigerate assembled sandwich for up to 2 hours but bread may become soggy.
Cook bacon and toast bread up to 1 hour ahead. Assemble just before serving to prevent sogginess.
Serve immediately while bread is still slightly warm and bacon is crisp for best texture contrast.
Common Mistakes
Don't skip the paper towels when microwaving bacon to avoid grease splatter and ensure even cooking.
Don't over-toast the bread to avoid rough texture that can hurt your mouth.
Don't skip salting the tomatoes to avoid watery sandwich filling.

FAQ
Can I cook the bacon in a pan instead of the microwave?
Yes, cook bacon in a skillet over medium heat for 6-8 minutes, turning once, until crispy. The microwave method is just faster and creates less mess.
How long will this sandwich keep if I need to pack it?
Pack components separately and assemble just before eating. The assembled sandwich will stay fresh for 2-3 hours refrigerated but may become soggy.
What if my avocado is too ripe or not ripe enough?
For underripe avocado, mash it slightly and spread like butter. For overripe avocado, mash completely and season with lemon juice and salt.
