Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Line baking tray with baking paper. Cut avocados in half lengthwise, remove the core. Brush cut surfaces with lemon juice. Cut off a piece of skin from the underside of the avocados so that they stand straight and firm on the tray.
Place on a baking tray, season cut surfaces with salt and pepper.
Beat the eggs one by one and let one egg slide into each hollow (some egg white may run onto the baking tray). Bake in a hot oven for about 20 minutes.
In the meantime, peel and finely dice the onion for the salsa. Wash and finely dice the tomatoes. Mix both. Season with salt, pepper, 1 pinch of sugar, vinegar and Tabasco. Stir in oil.
Cut the bacon into thin strips and fry them crisply in a pan without fat. Remove and let it drip off on kitchen paper. Remove avocados from the oven, season eggs with a little salt and pepper.
Sprinkle with bacon and add the salsa.
