ALIX'S TUNA PUFF
Serves 4.
Note: I found 6-ounce cans of tuna on sale for a dollar apiece, making the two cheaper than the 12-ounce can, so check prices as you shop. Cost per serving: $1.60.
• 1 sheet puff pastry, thawed according to directions
• 1 tbsp. or more Dijon-style mustard
• 1 (12-oz). or 2 (6-oz.) cans albacore tuna fish in water, drained, moisture pressed out and flaked
• 2 medium tomatoes, sliced
• Salt and pepper to taste
