Black coffee (1 piece), Cheddar or American Cheese (Reduced Fat, Pasteurized) (100 G), Salami (1 Slice (4 Inches Dia X 1/8 Inches Thick)) and Multigrain Bread (1 Regular Slice)

Make the multigrain bread the first target: reduce the portion to one slice or replace it with a dense pumpernickel or true sourdough rye bread, and check your response to the specific brand.

Try decaffeinated black coffee, half-caf, or drink coffee after rather than before the meal; caffeine can raise glucose in some people even without sugar.

Eat the cheese and salami before the bread, and eat the bread slowly as the last part of the meal rather than on an empty stomach.

Avoid adding sweetened creamers, flavored syrups, sweetened plant milks, ketchup, or sugary condiments; use mustard, vinegar, herbs, or unsweetened mayonnaise instead.

Add a non-starchy vegetable side such as salad greens, cucumber, tomato, broccoli, or peppers to increase meal volume and slow carbohydrate absorption.

Take a 10–20 minute easy walk or do light activity shortly after eating, if safe for you, and compare your glucose response across a few similar meals to identify whether coffee, bread amount, or their combination is the main trigger.
