Recipe serves four. It adds color to your plate, great flavor, and depending on what crumbs you use, can be low-fat (low-fat cheese works well, too), and can take on a variety of flavors.
4 medium tomatoes
salt and pepper
1/2 tsp crushed basil
1/2 tsp crushed oregano
1/3 c coarsely crushed cracker crumbs (or crouton crumbs)
1/3 c shredded Cheddar cheese (reduced fat, if desired)
Remove stem ends from tomatoes. Cut tomatoes in half horizontally. Trim ends to make the halves stand flat, if necessary. Arrange cut side up on microwaveable plate. Mix crumbs and herbs; mound evenly on tomatoes. Microwave uncovered on high for 2 minutes, rotating after 1 minute. Sprinkle cheese on top of tomatoes and either microwave 1 minute until cheese is melted, or transfer tomatoes to an appropriate pan to broil in the oven or toaster oven until the cheese is bubbly and begins to brown.
