Open can, discard lid. Hold a small wire mesh strainer or colander over an empty sink; dump can of tuna into
strainer, hold over sink until all of the liquid has drained. (To be sure all of the liquid has drained, gently
press on tuna in strainer with the back of a spoon.) Place tuna in a bowl, flake into small pieces with a fork. For
each tostada, gently press 1 tortilla into a microwave-safe soup or cereal bowl. Microwave on HIGH (100%) 20
seconds, to soften tortilla. Press with the back of a spoon to fit bowl. Break 1 egg into tortilla, microwave on
HIGH (100%) 40 to 50 seconds, until egg is barely set. Sprinkle with one-fourth of the tuna, 2 Tablespoons cheese
and 2 Tablespoons salsa. Microwave on HIGH (100%) 1 minute, check to see if egg is set. If not, microwave on HIGH
(100%) 20 to 30 seconds, until egg is set and cheese melted. Repeat with remaining ingredients.
